GoFundMe Plea For Ex-Trump Lawyer Cohen

Michael Cohen insists crowdfunding is the only way the whole truth can come out.

Donald Trump's former personal lawyer Michael Cohen is asking the public for help paying his legal bills, and one anonymous donor has already given $US50,000 ($A68,637) dollars.

Through his lawyer, the president's former "fixer" said collecting contributions through a GoFundMe page set up after his guilty plea this week is the only way to ensure the truth comes out about the president.

It is also the latest sign that Cohen is broke.

He owes at least $US1.4 million ($A1.9 million) to the Internal Revenue Service after pleading guilty on Tuesday to tax evasion, campaign finance violations and bank fraud, and has racked up millions of dollars in debt.

"He's without resources and owes a lot of money," lawyer Lanny Davis said in television interviews.

Cohen, who once said he would "take a bullet" for Mr Trump, said in court on Tuesday that the president directed him to arrange payments of $US130,000 ($A178,457) to porn star Stormy Daniels and $US150,000 ($A205,912) to former Playboy model Karen McDougal to buy their silence about alleged affairs before the election.

By Thursday afternoon, the GoFundMe page dubbed the "Michael Cohen Truth Fund" had raised more than $US145,000 ($A199,049) from about 2600 donations.

It has a goal of $US500,000 ($A686,375).
