Republican senators to watch as Trump prepares for new nominations

President-elect Donald Trump is announcing new nominees for his administration, many of whom will need Senate confirmation. He can afford to lose only three Republican votes if Democrats oppose a nominee. Some nominees, like Sen. Marco Rubio for Secretary of State, may receive bipartisan support. However, others, such as Pete Hegseth for Secretary of Defense and Matt Gaetz for Attorney General, are expected to face more challenges. Trump's party is more unified than during his first term, as some previous critics have left. Confirmation hearings are set to begin in January, with several Republican senators being key figures to watch.
