The House is set to welcome a number of high-profile celebrities when lawmakers return Tuesday, ranging from Olympic athletes to award-winning musicians. 

Lawmakers return to Washington, D.C., after a weeklong recess to resume legislative duties and advance a slate of must-pass spending bills. Meanwhile, the House will also hold hearings throughout the week featuring prominent athletes such as Michael Phelps to explore antidoping measures in Congress as well as socialite Paris Hilton to discuss institutional child abuse.
