US President-elect Donald Trump aims to make loyalist Kash Patel the next director of the Federal Bureau of Investigation, he said on Saturday, in a move that would mean replacing the agency's current leader.

Trump announced the former advisor and Pentagon official as his choice for the post on his Truth Social network.

The FBI's current director, Christopher Wray, was appointed to a 10-year term in 2017, meaning he would either need to step down or be fired.

The FBI under Wray -- who Trump appointed -- has investigated the incoming president, sparking Trump's ire.

"Kash is a brilliant lawyer, investigator and 'America First' fighter who has spent his career exposing corruption, defending Justice, and protecting the American People," Trump wrote on Truth Social.

A son of Indian immigrants, Patel served in several high-level posts during Trump's first term including as a national security advisor and as chief of staff to the acting defense secretary.

"Kash did an incredible job during my First Term," Trump said, adding that the nominee would work to "end the growing crime epidemic in America, dismantle the migrant criminal gangs, and stop the evil scourge of human and drug trafficking across the Border."

Appointment of allies

Wray was tapped by Trump during his first term, replacing an acting director after Trump fired former FBI director James Comey.

Separately, Trump nominated Chad Chronister, a Florida sheriff, as administrator of the Drug Enforcement Administration (DEA).

"Chad will work with our great Attorney General, Pam Bondi, to secure the Border, stop the flow of Fentanyl, and other Illegal Drugs, across the Southern Border, and SAVE LIVES," Trump wrote on Truth Social.

Bondi, a staunch Trump ally and former Florida attorney general, is the president-elect's pick to lead the Department of Justice.

The FBI is the investigative arm of the Department of Justice, while the DEA also falls under its purview.
