PHILADELPHIA (AP) — President Joe Biden scooped up endorsements from at least 15 members of the Kennedy political family during a campaign stop Thursday as he aims to undermine Donald Trump and marginalize the candidacy of independent Robert F. Kennedy Jr.

Kerry Kennedy, a daughter of former Attorney General Robert F. Kennedy, niece of former President John F. Kennedy and sister of the current presidential candidate, delivered the endorsements in Philadelphia by calling Biden “my hero.”

“We want to make crystal clear our feelings that the best way forward for America is to reelect Joe Biden and Kamala Harris for four more years,” she said.

She never directly mentioned her brother, but insisted “there are only two candidates with any chance of winning the presidency” this year, framing the campaign as a choice between Biden and Trump, with no room for a third party contender.
