U.S. officials are looking at the national security implications of the Chinese artificial intelligence app DeepSeek, White House press secretary Karoline Leavitt said on Tuesday, while President Donald Trump's crypto czar said it was possible that intellectual property theft could have been at play.

Trump’s national security adviser Mike Waltz had signaled before Inauguration Day that he would look to move holdover civil servants that served in the NSC during President Joe Biden’s administration back to their home agencies. The move is meant to ensure the council is staffed by those who support Trump’s agenda.
