Grimm's unfavorable reputation was drawn back into the news Monday when it was reported he would plead guilty to charges of tax evasion. Pelosi responded Tuesday by calling on House Speaker John Boehner (R-Ohio) to urge the embattled representative to remove himself from Congress.
"Clearly, Speaker Boehner must insist that Congressman Grimm resign immediately," Pelosi said in a Tuesday statement.
Voluntary resignation is the only way Grimm -- who was surprisingly re-elected to Congress in November despite previously being indicted on 20 counts of fraud -- would leave Congress. On Monday, the New York Daily News reported the congressman has the right to return to Congress so long as he doesn't face jail time.
The Daily News reported Grimm will enter the guilty plea on Tuesday afternoon in Brooklyn federal court to a felony charge of dodging taxes at a Manhattan restaurant he co-owned.
