A senior administration official said that John Kirby, a defense department press secretary, will move to the White House in a senior communications role with the National Security Council.
A source familiar with the decision said Kirby is expected to appear in the White House briefing room only occasionally in his new position.
Kirby's role in the White House remains unclear, as it is not clear how much Kirby will be at the White House. The source said that his briefing appearances would be similar to those of national security adviser Jake Sullivan or deputy Jon Finer.
The Pentagon and the White House don't want to make a statement.
Kirby's new position was first reported by the Washington Post.
He would arrive on the heels of Jen Psaki's departure as the White House press secretary. Karine Jean-Pierre replaced Psaki.
Kirby, the Pentagon's chief communication official, has been a top communications official for Defense Secretary Lloyd Austin and Deputy Defense Secretary Kathleen Hicks since the early days of the Biden administration.
