Former President Donald Trump has added his onetime campaign rival Robert F. Kennedy Jr. and the former Democratic Rep. Tulsi Gabbard to his presidential transition team, a spokesman confirmed Tuesday. Both Kennedy and Gabbard endorsed Trump in the past week in his race against Vice President Kamala Harris, the Democratic presidential nominee. "As President Trump's broad coalition of supporters and endorsers expands across partisan lines, we are proud that Robert F. Kennedy Jr. and Tulsi Gabbard have been added to the Trump/Vance Transition team," Trump campaign senior advisor Brian Hughes said in a statement to CNBC.
