It has been a US presidency like no other.
Almost four years of Donald Trump in the White House has brought the world some truly memorable moments and images that will go down in history.
As we get closer to finding out the results of the US presidential election, let’s take a look back at Mr Trump’s first term as President — from his inauguration to his 2020 campaign and much, much more.
On inauguration day of January 20, 2017, Mr Trump was sworn in as the 45th President of the United States.
Not long after he was formally sworn in, Mr Trump put a four-month hold on allowing refugees into the US and temporarily barred travellers with passports from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.
It was a move Mr Trump then said would protect Americans from terrorism.
Mr Trump nominated three people for the US Supreme Court in his term. His first pick was Neil Gorsuch.
At the time, Judge Gorsuch, 49, was the youngest nominee to the US Supreme Court in more than 20 years.
Mr Trump ordered the firing of a barrage of cruise missiles into Syria in retaliation for a chemical weapons attack against civilians back in April, 2017.
About 60 US Tomahawk missiles were fired from warships in the Mediterranean Sea.
Speaking after news of the launch emerged, Mr Trump said he called on “all civilised nations” to seek to end the bloodshed and slaughter in Syria.
He said the US missile attack was in the nation’s “vital national security interest”, arguing that the US must “prevent and deter the spread and use of deadly chemical weapons”.
Former FBI director James Comey was sacked by Mr Trump during an ongoing investigation into whether his campaign had ties to Russia meddling into the election.
A month later, Mr Comey testified at a US congressional hearing where he accused the President of firing him to try to undermine the bureau’s investigation into possible collusion.
The President also met Pope Francis at the Vatican.
At the time, the White House and the Vatican indicated the pair discussed terrorism, climate change and peace during their meeting.
During Trump’s presidency, an unforgettable clash between anti-racism protesters and white supremacist demonstrators occurred in Charlottesville, Virginia.
It left at least 34 injured and one person dead.
The violence came after a night where hundreds of white marchers with blazing torches marched through Charlottesville shouting “unite the right” and “you will not replace us”.
A year after former San Francisco 49ers quarterback Colin Kaepernick first knelt during the US national anthem — refusing to stand to protest police shootings of unarmed African-Americans — Mr Trump called on the National Football League to ban players from kneeling while the national anthem was played.
In October, 2017, devastating Hurricane Maria hit Puerto Rico and Mr Trump met survivors of the disaster in San Juan.
When Mr Trump met with former Japanese prime minister Shinzo Abe at the White House it made headlines, but for an unusual reason.
The pair were locked in a handshake that last 19 seconds and President Abe’s reaction was hard to forget.
At the time, Mr Trump was accused of dealing a “death sentence” to the Middle East peace process by recognising Jerusalem as Israel’s capital.
Leaders around the world, including US allies, condemned the move as US embassies in the Middle East and Europe braced for potentially violent protests after the announcement.
In a speech at the White House, Mr Trump said his administration would also begin a process of moving the US embassy in Tel Aviv to Jerusalem.
In his first year of office, Mr Trump had a sweeping tax bill approved by the US House of Representatives.
The bill slashed taxes for corporations and the wealthy while giving mixed, temporary tax relief to middle-class Americans.
Mr Trump, who had emphasised a tax cut for middle-class Americans during his 2016 campaign, said at the start of a cabinet meeting before the vote that lowering the corporate tax rate from 35 per cent to 21 per cent was “probably the biggest factor in this plan”.
After a deadly shooting at a Florida high school in 2018, in which 17 people were killed, survivors of the shooting began calling for more gun control in the US.
One of them was survivor Emma Gonzalez, who was a year 10 student at the time and attended Marjory Stoneman Douglas High School where the massacre took place.
Ms Gonzales became a well-known figure after she delivered an impassioned speech in front of thousands at an emotionally charged anti-gun rally in Florida and where she also called out Mr Trump for his ties to the National Rifle Association.
Mr Trump later hosted a listening session with six students from Marjory Stoneman Douglas High School.
He sat in the middle of a semi-circle in the White House State Dining Room, listening intently as survivors and parents wept and delivered emotional appeals for change.
During the session, Mr Trump said he’d act on background checks, mental health and endorsed arming teachers with firearms.
In a tell-all interview with America’s 60 Minutes program, porn star Stormy Daniels (whose real name is Stephanie Clifford), claimed she not only had unprotected, consensual sex with Donald Trump in 2006, but was subsequently threatened to keep it quiet.
Ms Daniels said her lawyer came to her with a deal from Mr Trump’s former lawyer Michael Cohen to accept $130,000 to not tell her story.
A United States-bound caravan of thousands of mostly Honduran migrants entered Mexico in 2018, defying threats from Mr Trump that he would close the US-Mexico border if the caravan advances.
Some travel more than 4,000km over five weeks to reach the US and are met with tear gas at the border wall.
Mr Trump said it was “a very minor form of the tear gas itself” that he assured was “very safe”.
Amid the migrant situation, first lady Melania Trump visited a Texas facility which houses migrant youth separated from their parents.
But it was her jacket that made headlines. She wore a cargo jacket with the words, ‘I really don’t care. Do u?’ scrawled on the back.
In June of 2018, a historic meeting took place between Mr Trump and North Korean leader, Kim Jong-un.
The pair met in Singapore and signed a document pledging to work toward complete denuclearisation of the Korean peninsula.
“I feel really great. We’re going to have a great discussion and will be tremendously successful,” Mr Trump said on the day.
Days after meeting with Mr Kim, the US President met with another powerful world leader, his Russian counterpart Vladimir Putin.
The pair met at a summit in Helsinki, Finland where they spoke for more than two hours one-one-one with only translators present.
Mr Trump said: “The world wants to see us get along”.
And that the two countries have “great opportunities”, and while they had not got along for the past few years, they could have an “extraordinary relationship”.
Back home in the US, Mr Trump met with American rapper Kanye West during an appearance in the Oval Office.
Surrounded by press, West credited Mr Trump with preventing a war with North Korea and encouraged him to swap his usual Air Force One for a hydrogen-powered plane.
Mr Trump described West as a “smart cookie”.
In July, 2018, Mr Trump nominated Judge Brett Kavanaugh to the US Supreme Court to fill the position vacated by retiring associate justice Anthony Kennedy.
Multiple women then came forward with accusations of sexual assault against Judge Kavanaugh, including psychology professor Christine Blasey Ford.
The nomination ultimately went ahead, with the full Senate confirming Justice Kavanaugh by a vote of 50-48 in October.
In December 2018 Mr Trump’s ex-lawyer Michael Cohen was sentenced to three years in prison for his role in making illegal hush-money payments to women to help the President’s 2016 election campaign .
Mr Cohen was also found to have lied to Congress about a proposed Trump Tower project in Russia.
After Mr Trump announced the withdrawal of almost 2,000 US troops in Syria, and the White House declared victory in the mission to defeat Islamic State militants there, he visited soldiers stationed in Iraq on Boxing Day.
He was accompanied by the first lady during the unannounced trip.
US Defence Secretary Jim Mattis abruptly resigned following the announcement to withdraw troops from Syria at the time.
While Mr Trump was in Iraq, the US Government remained in lockdown.
Government employees were sent home or obligated to work without pay as Congress refused to meet Mr Trump’s demands to fund his long-promised wall at the US-Mexico border.
The promise of a border wall was a central component of Mr Trump’s presidential campaign.
In his second State of the Union address, The President called for bipartisanship and cooperation.
“We must reject the politics of revenge, resistance, and retribution, and embrace the boundless potential of cooperation, compromise, and the common good,” he said.
But it was Democratic House Speaker Nancy Pelosi who made the biggest statement of the night with a distinctive clap she gave the President.
A few months later at a Conservative Political Action Conference Mr Trump veered off script to launch a tirade about events that led to the Russia investigation.
In a speech that lasted more than two hours, he spoke out against special counsel Robert Mueller ahead of his report on alleged Russia collusion by the Trump campaign in 2016 and said his political opponents were “trying to take me out with bullshit”.
During a state visit to the UK, Mr Trump visited Buckingham Palace and attended a state banquet.
He was accompanied by the first lady, daughter Ivanka and her husband Jared Kushner.
Not long after his state visit, Mr Trump became the first sitting US president to step into North Korea as he met the north’s leader, Kim Jong-un, in the Korean demilitarised zone.
Rescue officials reported scenes of utter ruin in parts of the Bahamas in the wake of Hurricane Dorian in September 2019, the most powerful storm on record to hit the islands.
As the hurricane raged, Mr Trump came under fire for repeatedly claiming that parts of Alabama could be hit by the giant storm.
He answered “don’t know” when asked why a weather map he showed to reporters in the Oval Office had apparently been altered to back up his claims about the path of Hurricane Dorian.
The following month, Mr Trump announced that Islamic State leader Abu Bakr al-Baghdadi “blew himself up” after being cornered by US forces in northern Syria.
“Last night, the United States brought the world’s number one terrorist leader to justice,” Mr Trump said.
The confirmation came a day after Mr Trump had tweeted that: “Something very big has just happened!”
At the beginning of 2020, Mr Trump launched Space Force, making it the first new US military service in more than 70 years.
A month later he was acquitted of both charges against him in the Senate impeachment trial.
The charges were abuse of power and obstructing Congress.
As 2020 went on, the world was in full swing, dealing with a new virus — COVID-19.
While battling with mass deaths, cases and lockdowns, Mr Trump worked alongside health expert Dr Anthony Fauci, who assumed national prominence as a leader in the fight against the coronavirus.
He contradicted or corrected Mr Trump on scientific matters during the public health crisis.
And while campaigning in October, Mr Trump said: “Fauci is a disaster. If I listened to him, we’d have 500,000 deaths.”
Mr Trump held the Republican National Convention at the White House in late August.
At the conclusion of the convention, guests were met by angry protesters as they left the grounds of the White House.
Protests after the death of George Floyd continued to rage on across the country and just outside the White House.
Amid protesters in Washington, Mr Trump walked from the White House to the historic Saint John’s Episcopal Church, during which the President held up a bible for photographers.
Authorities cleared the way for him, using tear gas and rubber bullets to disperse protesters.
After the death of Ruth Bader Ginsburg, Mr Trump nominated Judge Amy Coney Barrett to replace her seat on the US Supreme Court.
A Rose Garden function at which Mr Trump announced Judge Barrett’s nomination was later identified as a coronavirus superspreader event, with many attendees, including the President, going on to test positive.
Twenty-four hours after announcing his diagnosis, Mr Trump left the White House by helicopter for Walter Reed National Military Medical Center, where he spent three days.
While still infectious, he briefly left the hospital in a bulletproof SUV to wave at supporters gathered outside, accompanied by Secret Service agents clad in masks and personal protective equipment.
After leaving hospital, Mr Trump soon recommenced election campaigning and holding rallies, claiming without evidence he was now immune from coronavirus.
The second presidential debate against Joe Biden was cancelled after Mr Trump refused to take part in a virtual debate, which was hastily organised in light of his coronavirus diagnosis.
The final presidential debate played out more like a traditional debate than almost anyone expected, featuring more patient political sparring than the wild scenes of the first clash.
Democrats opposed Amy Coney Barrett’s nomination to the Supreme Court, alleging hypocrisy given Republicans refused to confirm Barack Obama’s pick during an election year in 2016.
Ms Barrett faced days of questioning from US senators at her Supreme Court confirmation hearing on abortion, the Affordable Care Act, presidential powers, climate change, voting rights, and other issues.
She declined to give her personal views or preview how she might rule if confirmed to the court.
A week before election day, Judge Barrett was confirmed to the Supreme Court, with the Senate voting largely along party lines and confirming a 6-3 conservative majority on the bench.
