Former Trump attorney Michael Cohen will testify before three congressional committees before he goes to prison on March 6, his lawyer confirmed Wednesday.

"Cohen committed to all three committees that he would voluntarily testify before the end of the month," Cohen's attorney Lanny Davis said in a statement released Tuesday night.

CNBC first reported Wednesday that Cohen will testify before the House Oversight and Reform, Senate Intelligence and House Intelligence committees. Only his testimony from the Oversight and Reform Committee will be made public.

Cohen was supposed to testify before Congress this week, but told lawmakers he could not for medical reasons.

"He's already stiffed us on being in Washington today because of an illness," Burr added. "Yet on Twitter, a reporter reported he was having a wild night Saturday night eating out in New York with five buddies, didn't seem to have any physical limitations. And he was out with his wife last night."

Cohen's attorney defended his medical reasons in a statement on Tuesday night.

“Despite Senator Burr’s inaccurate comment, Mr. Cohen was expected to and continues to suffer from severe post shoulder surgery pain," Davis said. "The medication Mr. Cohen is currently taking made it impossible for him to testify this week.

"We believe Senator Burr should appreciate that it is possible for Mr. Cohen to be in pain and still have dinner in a restaurant with his wife and friends.”
