Sen. John Fetterman, D-Pa., returned to the Senate Monday in a black hoodie and shorts, after a six-week stay in the hospital where he was treated for clinical depression.

As the senator entered the Capitol for one of the first times since taking office in January, he refused to take questions from the press. 

"It’s great to be back. Thank you," Fetterman reportedly said as he walked into the building.

Fetterman will chair his first subcommittee hearing days after returning from his weeks-long absence

Fetterman was reportedly using a closed captioning device that types out what is being said to him so that he can have conversations with other members of Congress.

The New York Times reported Fetterman's severe hearing disability even caused him to hear the voice of the teacher from the "Peanuts" cartoon when listening to people speak.
