White House spokesperson Sarah Sanders called it "laughable" that anyone would take Cohen's testimony seriously.
"Disgraced felon Michael Cohen is going to prison for lying to Congress and making other false statements. Sadly, he will go before Congress this week and we can expect more of the same," Sanders said in a statement, adding that it was "pathetic to see him given yet another opportunity to spread his lies."
Cohen is expected to reveal details related to a hush-money payment to a porn star who had an alleged affair with Trump, the Wall Street Journal reported, citing a person familiar with Cohen’s testimony.
Cohen is scheduled to deliver public testimony before the US House of Representative Committee on Oversight and Reform on February 27. The following day, Cohen will appear in a closed session before the US House Intelligence Committee. Cohen arrived in Congress earlier on Tuesday to testify during a closed session of the Senate Intelligence Committee.
Cohen has been sentenced to a three-year prison term for tax fraud and crimes that involve hush-money payments to two women Trump had allegedly affairs with, in violation of campaign laws, as well as lying to Congress. He remains out of prison to continue cooperating with Special Counsel Robert Mueller's probe of Trump associates during the 2016 presidential campaign.
