A pesky rat has infiltrated the group house inhabited by Senate Democratic leaders Charles E. Schumer of New York and Richard J. Durbin of Illinois, and owned by Rep. George Miller of California, CQ Roll Call has learned.

A source close to the situation said multiple traps have been set up throughout the Capitol Hill “Animal House” to catch the rodent. Schumer was overheard on his cellphone in the Capitol discussing exterminators. The rat situation has been ongoing for days, our source tells us.

“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.

No one would confirm whether the frat-like lifestyle of the prominent Democrats led to the rat’s break-in, but a 2011 NBC special “Inside Congress” filmed the lawmakers in their home and featured Miller chiding Schumer to “close up the cereal before you leave.”

Modest suggestion from your friends at CQ Roll Call, senators, check under the gross couch!
