The White House National Security Council's strategic communications coordinator, John Kirby, will be promoted to national security adviser and appointed assistant to US President Joe Biden.
Kirby will be responsible for coordinating national security communications across the various departments, it said.
He will also lead a separate group of the press service of the National Security Council, which will continue its daily press operation as usual.
Anita Dunn, senior adviser to US President Joe Biden, noted that "Kirby's decades of high-level national security experience and clear strategic vision make him a very valuable communicator and advisor to this team."
