Sen. Ted Cruz’s (R-TX) Tuesday evening endorsement of former President Donald Trump’s 2024 bid marked a significant moment for the Senate Republican Conference. 

Cruz was the 25th senator to endorse Trump in the primary, officially securing him the support of the majority of Senate Republicans, of whom there are 49. While more than half of House Republicans, including most of the party leaders, were quick to throw their support behind Trump last year, Senate endorsements have trickled in at a slower pace.
