A pair of funny sanitation workers (guest stars Sal Vulcano and James Murray; "Impractical Jokers") discover the shredded body of a U.S. Senator in a street sweeper, which leads Brennan, Booth and the team to Capitol Hill, where they meet with U.S. Senator and majority whip Hayley Winters (guest star Brenda Strong) and the victim's chief of staff Eric Morales (guest star Nicholas Gonzalez) to get to the bottom of this political murder. Meanwhile, as Aubrey starts to develop a relationship with squintern Laura (Jessica Warren), he looks into her past to make sure nothing will harm his dream of a future in politics.
