NEW YORK, March 20 (Reuters) - A federal judge on

Wednesday declined to sanction Michael Cohen, the former lawyer

and fixer for Donald Trump, for mistakenly giving his lawyer

fake case citations generated by artificial intelligence, while

calling the episode "embarrassing" for the lawyer and Cohen

himself.

U.S. District Judge Jesse Furman in Manhattan also refused

to end court-supervised release for Cohen, who pleaded guilty in

2018 to campaign finance violations and later served time in

prison, and suggested that Cohen may have perjured himself.

The decision came as Cohen prepares to be a star witness

against Trump in the former president's upcoming criminal trial,

concerning whether Trump covered up hush money payments to porn

star Stormy Daniels to aid his successful 2016 presidential run.
