Three of President Donald Trump’s most controversial Cabinet 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.

Robert F. Kennedy Jr. will stand before the Senate Finance Committee on Wednesday and the Senate Health, Education, Labor and Pension Committee Thursday as President Donald Trump's nominee to lead the Department of Health and Human Services.
