U.S. Sen. Charles Schumer, D-N.Y., doesn’t just smell a rat in his Washington, D.C., townhouse. He’s living with one, according to his office.

Schumer, who shares a Capitol Hill row house with his Senate colleague Dick Durbin, D-Ill., has gone all-out to eradicate the rat from his digs. Mouse traps have been deployed in the home, which is owned by U.S. Rep. George Miller, D-Calif.

New York’s senior senator quipped that should the extermination fail, he hopes the rat sticks to Durbin’s side of the so-called Animal House apartment.

“Durbin and I are united in our hopes that it’s dead, but if it’s not, I hope it’s upstairs and he hopes it’s downstairs,” Schumer said in a statement, according to Roll Call.

The two-bedroom townhouse was profiled by ABC News in 2007. Schumer likened the place to his fraternity digs in college.

"I'm sure [voters] think we live in big mansions down here with a lot of servants," the senator said at the time.

Durbin added that the house isn’t exactly squeaky-clean, which may explain the current rat situation.

"There's just something about living in filth and squalor," Durbin said in 2007. "It's been called 'Animal House.'"

The apartment back then was shared by Schumer, Durbin, Miller and then-U.S. Rep. Bill Delahunt, D-Mass. Miller no longer lives there, but he continues to rent out the place to the two senators.
