President Joe Biden launched the first rally of his 2024 presidential campaign Saturday, speaking to a crowd in Philadelphia, Pennsylvania.

The president officially announced his reelection bid April 25, though some critics became concerned about his lack of campaign events. The political rally was hosted by union members at the Philadelphia Convention Center while Pennsylvania Democratic Sens. John Fetterman and Bob Casey, as well as other officials including Rep. Bob Casey, joined the president. The president received the backing of labor union AFL-CIO, the largest federation of unions in the country,

In his remarks, Biden spoke about his legislative success, the importance of building products in America, his budget proposal and getting the wealthy to “pay their fair share.” He also highlighted how he “negotiated” with Republicans during his State of the Union speech to not cut Social Security and Medicare, a story he has repeated frequently.

“I truly believe this country is about to take off” and the investments made in the last three years will create growth “for the next five decades,” Biden said, adding that union members will get all the credit.

Biden accused Republicans of going after union members, saying they “are coming for your jobs” and “your future,” but did not mention any candidates by name. (RELATED: Biden Finishes Speech With ‘God Save The Queen’ For No Apparent Reason)
