Grimm was charged Monday in a 20-count indictment that accuses him of under-reporting the payroll and earnings of the Upper East Side restaurant, Healthalicious, which he ran from 2007 to 2010. Chief Investigative Reporter Jonathan Dienst reports.
Grimm's lawyer, William McGinley, suggested last week the charges were "politically driven."
"We are disappointed by the government's decision, but hardly surprised. From the beginning, the government has pursued a politically driven vendetta against Congressman Grimm and not an independent search for the truth," McGinley said. "Congressman Grimm asserts his innocence of any wrongdoing. When the dust settles, he will be vindicated."
One of Grimm's fundraisers was arrested earlier this year by the FBI and is accused of using straw donors to funnel more than $10,000 into his campaign. Grimm has not been accused of any wrongdoing in that case, which is still under investigation.
In January, Grimm erupted at a local TV reporter on camera and threatened that he would "break you in half, like a boy" after the State of the Union address when he was asked about the federal investigation into his campaign finances.
He later apologized.
