JOE AND HUNTER BIDEN
Donald Trump has always made fun of his political opponent, calling him "Sleepy Joe," but it was his unsubstantiated claims about Hunter Biden's business dealings in Ukraine that backfired, triggering his own impeachment inquiry. But it's not like the Bidens weren't warned. Mr Trump tweeted in April, "Welcome to the race Sleepy Joe … It will be nasty."
HILLARY CLINTON
Mr Trump has always reserved a special kind of hate for his defeated Democrat opponent Hillary Clinton, calling her "crooked Hillary" whenever he mentions her, which is often — it's estimated that he has tweeted about her more than 350 times and he was at it again just last month.
ANDREW CUOMO
According to the US President, New York City is falling apart because of its rising number of homeless … and also, possibly, because New York State has applied pressure on Trump to provide his financial records. Which of course might be why the Governor of New York State is insane.
SPIKE LEE
When the respected black filmmaker made his acceptance speech for winning an Oscar for BlacKkkKlansman, he urged viewers to vote against Trump in the 2020 election. Trump responded by calling Lee out on Twitter: "Be nice if Spike Lee could read his notes or better yet not have to use notes at all when doing his racist hit on your president."
THERESA MAY
Trump had to have a go at the former British PM for "how badly" she handled Brexit, suggesting that he could have done a better job.
JOHN MCCAIN
No one, not even the dead, are immune from Trump's Twitter tirades. Even the late US Senator John McCain was the butt of his insults, and the deceased senators daughter Meghan weighed in.
DEBRA MESSING
Trump escalated a feud with the left-leaning Will & Grace star claiming that she was in fact a "racist." Trump posted, "Bad 'actress' Debra The Mess Messing is in hot water. She wants to create a 'Blacklist' of Trump supporters, & is being accused of McCarthyism. Is also being accused of being a Racist because of the terrible things she said about blacks and mental illness. If Roseanne Barr said what she did, even being on a much higher rated show, she would have been thrown off television."
BETTE MIDLER
When Bette Midler had the misfortune of retweeting a fake quotation (and apologised), Mr Trump was quick to pounce on his old adversary, calling her a "washed up psycho" for the simple mistake.
BARACK OBAMA
Donald Trump has nothing good to say about former US president Barack Obama, but in a string of tweets posted just after Christmas, he retweeted a Christian meme, suggesting that Obama was the Antichrist.
ALEXANDRIA OCASIO-CORTEZ
Freshman US senator Alexandria Ocasio-Cortez is unapologetically left-wing, which immediately earns the ire of the US president, leading to some pretty intense twitter spats between them. He calls her a "whack job," she calls him a "criminal".
ROSIE O'DONNELL
Trump's feud with the out lesbian comedian goes back for years (he called her "disgusting", she accuses him of being a bully), but he reignited it again with a Make America Great Again video mashup he tweeted which shows the POTUS in a battle against Amy Schumer, the Clintons, O'Donnell and Obama. However, the video violated copyright and was taken off the internet.
NANCY PELOSI
In retaliation against the Speaker of the House spearheading the impeachment inquiry against him, Mr Trump took aim at "Crazy Nancy's own district in California as "one of the worst anywhere in the U.S. when it come to the homeless & crime. It has gotten so bad, so fast – she has lost total control and, along with her equally incompetent governor, Gavin Newsom, it is a very sad sight!"
CHRISSY TEIGEN
Trump's Twitter feuds were probably the most bitter with Chrissy Teigen, the wife of John Legend, with the US President calling her "filthy-mouthed" after Teigen called him a "pussy ass bitch".
GRETA THUNBERG
Sadly, the US President thought it was fair to take aim at a child activist, Swedish environmentalist Greta Thunberg. "She seems like a very happy young girl looking forward to a bright and wonderful future," Mr Trump sarcastically tweeted following Thunberg's speech in front of the United Nations General Assembly earlier this fall. "So nice to see!"
ELIZABETH WARREN
Based on her claim to have Native American ancestry, Mr Trump nicknamed her "Pocahontas", and he even admitted to that fact!
