Kash Patel, who previously served as an aid to the House Intelligence Committee's Devin Nunes, was appointed to be a senior adviser to new acting Director of National Intelligence Richard Grenell.
A source told CBS News that there is a new mandate to clean house, including a “top to bottom” review of ODNI operations that have expanded since 2005. Patel's move was first reported by Politico.
President Trump announced on Wednesday that Grenell, the U.S. ambassador to Germany and a Trump loyalist, would replace Joseph Maguire as acting DNI.
