U.S. Sen. John Fetterman, D-Pa., has co-sponsored four pieces of legislation in his first week in office.

The bills will aim to expand access to critical health care services, combat gun violence by getting assault weapons off streets, improve wages for federal employees, and provide District of Columbia citizens proper representation in Congress, according to a news release from Fetterman’s office.

“I was proud to hit the ground running in D.C. and co-sponsor these vital pieces of legislation,” Fetterman said. “These bills all deliver on promises I made during our campaign, to combat gun violence, expand health care services, improve wages, and increase voting rights and representation for people across the country.”

On Thursday, Fetterman announced his assignments to Senate committees on Agriculture, Nutrition, and Forestry; Banking, Housing, and Urban Affairs; and Environment & Public Works.
