Watch live: Senate confirmation hearings for Trump cabinet picks begin

As the first confirmation hearings for Donald Trump's new administration are set to start this week, the president-elect announced several new nominees Saturday who share one thing in common: they all served in Trump's first term. The latest picks would work across a range of departments that deal with veterans, small businesses, energy, the environment, transportation and national parks. They would take on crucial support roles for Trump's nominees to head various departments. The process of confirming or rejecting some of Trump's most high-profile cabinet selections will enter a crucial stage Tuesday as senators begin assessing several nominees at public hearings, including Defense Secretary nominee Pete Hegseth. He's expected to face questions about allegations of sexual assault, excessive drinking and more.
