Kash Patel, President Donald Trump’s pick to lead the FBI, is to encounter deeply skeptical questioning from Democratic senators about his loyalty to the president and stated desire to overhaul the bureau as he faces a high-stakes hearing that will help determine his path toward confirmation.

Robert F. Kennedy Jr., President Donald Trump's pick to lead the top U.S. health agency, came under attack for his anti-vaccine views at a contentious Senate confirmation hearing on Wednesday, with one senior Democrat saying he embraced conspiracy theories and "quacks" to dissuade use of lifesaving medicines.

Kash Patel, President Trump's nominee to serve as FBI director, is set to appear Thursday on Capitol Hill for a high-stakes confirmation hearing before the Senate Judiciary Committee amid calls from Republicans for massive reforms in FBI leadership and concerns from Democrats about his fitness to lead the nation's top law enforcement agency.
