Michael Grimm being endorsed by the UFOA this morning.

There were a flurry of new stories about Congressman Michael Grimm this weekend, most notably an Associated Press report that the FBI is considering setting up a formal investigation into Mr. Grimm's fundraising, but the Staten Island Republican is pressing forward with his reelection campaign at full speed. He announced his second union endorsement this morning, this time from the Uniformed Fire Officers Association.

“The Unformed Fire Officers Association, representing active and retired New York City Fire Officers, is proud to endorse Congressman Michael Grimm for re-election to the United State's New York’s 13th District,” UFOA President Al Hagan said in a statement.

Mr. Hagan connected Mr. Grimm's own uniformed biography to the endorsement.

“Joining the United States Marine Corps, Michael Grimm was willing to fight for the freedoms we all enjoy as Americans. As a FBI Agent, Michael fought to uphold the law. As a 9/11 first responder he worked alongside our brothers in the FDNY as a proud New Yorker," he said. "The Unformed Fire Officers Association looks forward to a long, productive relationship with Congressman Michael Grimm in the months and years to come.”

The UFOA endorsed Mr. Grimm's Democratic opponent in his last campaign, however, political insiders told The Politicker the union tends to favor incumbents.

It's unclear if Mr. Grimm spending a day in the life of a firefighter played any role in the union's endorsement process.
