An associate of U.S. President Donald Trump's personal lawyer, Rudy Giuliani, on Monday urged a judge to let him stay free on bail while he awaits trial, denying prosecutors' accusations that he lied about receiving a $1 million payment from Russia shortly before he was arrested.

A lawyer for Lev Parnas, who is charged with campaign finance crimes, said the payment was a loan to Parnas' wife, and that it had been disclosed to authorities before his bail was set.

"At no time did Mr. Parnas make a knowingly false statement," Parnas' lawyer, Joseph Bondy, said in a filing in Manhattan federal court.
