MICHAEL Avenatti, the lawyer for porn actress Stormy Daniels, says he now represents three additional women who he says had relationships with President Donald Trump and were paid “hush money” before the 2016 presidential election.

Avenatti disclosed the information on Thursday at a community forum in West Hollywood, California, but he would not provide additional information.

Asked if he had evidence the women had relationships with Trump, Avenatti said: “Yes”.

The claims come as Trump’s own lawyer, Michael Cohen, made his own claim that the president knew members of his election campaign team were meeting with a Russian lawyer — directly contradicting Trump’s own statements.

He said he was “not at liberty to share” the evidence because he did not have permission from his clients to disclose specifics.

But Avenatti said the women, who contacted him months ago, were “paid hush money prior to the 2016 election”.

He called on Trump and his former longtime personal lawyer, Michael Cohen, to come forward and disclose information about the women and their supposed relationships with Trump.

Trump’s lawyer, Charles Harder, did not immediately respond to an email seeking comment.

Daniels, whose real name is Stephanie Clifford, has said she had sex with Trump in 2006, when he was married, but Trump has denied it.

Days before the 2016 presidential election, she was paid $US130,000 ($A175,000) to stay silent in a deal handled by Cohen.

She is suing to invalidate the nondisclosure agreement.

Cohen’s lawyer, Lanny Davis, would not say if he knew whether Cohen had been involved in any other hush-money deals on behalf of Trump.
