HARRISBURG, Pa. (AP) — Pennsylvania’s Democratic U.S. Sen. Bob Casey is endorsing Joe Biden for president, just minutes after the former vice president entered the crowded 2020 race.

In a statement Thursday, Casey touted Biden as a fighter for the middle class who can beat President Donald Trump in Pennsylvania if Biden becomes the Democratic nominee.

Biden is heading to Philadelphia later Thursday for a fundraiser.

He’s backed by city party elders, including former Gov. Ed Rendell, who once called Biden “Pennsylvania’s third senator” because of his willingness to help Democrats in the state when Pennsylvania had two Republican senators.
