Robert F. Kennedy Jr. has suspended his independent presidential campaign and endorsed Donald Trump, potentially giving Trump a slight boost among Kennedy’s supporters.

Kennedy made the announcement during a rally in Arizona, where he joined Trump onstage to loud cheers.

Kennedy cited issues like free speech and the war in Ukraine as reasons for his endorsement, though he hasn’t formally ended his campaign and will remain on the ballot in some states.

His decision has sparked controversy, especially among his family members, who have expressed disappointment, the Associated Press has reported.

Kennedy’s endorsement marks a surprising alliance between a member of the storied Kennedy family and Trump, as Kennedy shifts from his initial run as a Democrat to supporting the Republican nominee.
