Trump told the Sunday Times in an interview that Britain should "walk away" from talks and refuse to pay a £39 billion ($49 billion) divorce bill if it doesn't get better terms from the EU.
The president also says Brexit party leader Nigel Farage, an outspoken advocate of leaving the EU without a deal, should be given a role in the negotiations.
He told the newspaper that Farage "is a very smart person. They won't bring him in. Think how well they would do if they did. They just haven't figured that out yet."
Britain is scheduled to leave the EU on Oct.31 unless both sides agree to an extension. Britain's position is in flux because Prime Minister Theresa May is stepping down as party leader on Friday, setting in motion a race to succeed her and become prime minister.
Trump's comments come just before he begins a state visit Monday to Britain, hosted by Queen Elizabeth II. He will meet with May on Tuesday.
Trump has also taken the unusual step of saying that Conservative Party leadership candidate Boris Johnson would make an "excellent" leader for the UK.
It is traditional for US and other world leaders not to offer choices in other country's domestic political competitions.
US Ambassador Robert "Woody" Johnson said on Sunday that Trump's support of Johnson stems from their personal relationship.
"He's known Boris Johnson for a long time and what he's commenting on is his knowledge of Boris Johnson as a person," the ambassador said.
He also said that Washington would be ready to sign a strong trade deal with Britain once it's out of the EU.
It’s unfortunate to have to do this as early as the very first sentence but just so you know, the forthcoming column is nominally a work of satire. It is my job to make fun of politicians, to point out the hypocrisy and absurdity of what they’re up to.
Although recent events haven’t been too kind to Boris Johnson or shone a positive light on his leadership skills, there was a time in the not too distant past when he was the candidate that united the Conservative Party.
British Prime Minister Boris Johnson spoke to US President Trump on Monday, discussing Brexit, trade and economic issues, a statement from Johnson’s office said.
His Highness Sheikh Saud Bin Saqr Al Qasimi, Member of the Supreme Council and Ruler of Ras Al Khaimah visited the Sharjah Research, Technology and Innovation Park (SRTIP) on Monday, where he was given a comprehensive briefing on the services and solutions offered to local and international companies and projects within and outside the UAE.
Conservative media tycoon Rupert Murdoch will tie the knot for the fifth time, at the age of 92 years, he said on Monday in an interview with his own newspaper, the New York Post.
The company said in a statement that it had declared "a state of emergency following an oil spill in the west of the country," noting that "there were no injuries resulting from the leak and that production operations were not affected."
Chinese President Xi Jinping met his "dear friend" Vladimir Putin in Moscow on Monday, seeking both to deepen economic ties with an ally he sees as a useful counterweight to the West and to promote Beijing's role as a potential peacemaker in Ukraine.
