Rep. Michael Grimm (R-N.Y.) will plead guilty Tuesday to a felony charge of cheating on his taxes at a Manhattan restaurant he co-owned before he was elected to Congress, the New York Daily News reported Monday.

In April, a 20-count federal indictment accused Grimm of hiring undocumented immigrants and hiding more than $1 million in sales and wages at his restaurant. The congressman, who was re-elected in November, had pleaded not guilty to those charges. His trial was scheduled to begin in February.

But according to the Daily News, Grim will enter the guilty plea in Brooklyn federal court Tuesday at an afternoon hearing.

During his campaign, the congressman said that he would resign from Congress if he was “unable to serve.” He was first elected to the chamber in 2010.

He remains under investigation by the Department of Justice and stepped down from his seat on the House Financial Services Committee.

In January, Grimm garnered more negative headlines when he threatened to break a reporter in half and throw him off of a balcony after President Barack Obama's State of the Union address.

Grimm's attorney has accused the federal government of pursuing a "politically driven vendetta" against the representative.
