New York Rep. Michael Grimm said today his campaign headquarters was “vandalized and burglarized.“

In a statement, the freshman Republican called the alleged crime “a disgraceful act of cowardice” and a “heinous act” that “represents an assault on democracy and the political process.”

The campaign said three plate glass windows were broken and private campaign data was tampered with at the Staten Island headquarters, leaving a server “corrupted and erased.”

The New York Police Department responded to Roll Call’s inquiries tonight with the following statement: “The campaign HQ of Rep. Michael Grimm, 2582 Hylan Blvd., had three windows broken between 19:30 hours on Sept 22 and 10:00 hours on Sept 23rd. It is being investigated as a criminal mischief. NYPD computer crimes will investigate further any assertions that computers there were tampered with.”

Grimm faces Democrat Mark Murphy on the ballot in November. Roll Call rates the 11th district race as Leans Republican.
