President Donald Trump endorsed Republican Jack Ciattarelli in New Jersey's GOP primary, saying he's gone “ALL IN” on the “Make America Great Again” agenda. Trump's endorsement came Monday in a Truth Social post and gives Ciattarelli's campaign a boost as he competes against two other Trump supporters and a state senator who has been critical of the president. The president's endorsement and Ciattarelli's gratitude to Trump in a social media post of his own reflect the president's influence in the party, even in Democratic-leaning New Jersey.
