US President-elect Donald Trump has picked a former aide, Kash Patel, to lead the Federal Bureau of Investigation, an agency Patel has often criticised.
A former US defence department chief of staff in the first Trump administration, Patel has been a steadfast supporter of the incoming Republican president.
For Patel to take the job, the current FBI director Christopher Wray would need to resign or be fired - although Trump did not call on him to do so in his post.
Separately, Trump said he plans to nominate Chad Chronister, sheriff of Florida's Hillsborough County, as head of the Drug Enforcement Agency.
