Robert F. Kennedy Jr. is widely expected to drop out of the presidential race Friday and endorse Donald Trump. RFK Jr. is addressing his supporters from Phoenix Friday; Trump is also scheduled to be in Arizona then. RFK Jr. initially launched his campaign as a Democratic challenger to Biden before running as an independent, but recent reports say he courted both Harris and Trump for a future job. On Tuesday, Jack Schlossberg, grandson of John F. Kennedy and cousin to RFK Jr., addressed the DNC and declared his support for the Harris-Walz ticket.
