Robert F. Kennedy Jr., Tulsi Gabbard and Kash Patel testify before Senate committees on Capitol Hill on Thursday as urgency builds to confirm President Donald Trump’s Cabinet nominations.

Three of President Donald Trump’s most controversial nominees faced sharp questions in the Senate during hearings Thursday from Democrats as well as several Republican senators in what amounted to the most direct skepticism from GOP senators over Trump’s nominees to date.

The confirmation battles over Tulsi Gabbard and Robert F. Kennedy Jr. will be a test of how much Trump has changed the Republican Party.
