The Trump administration sought to put the scandal over its use of the Signal messaging app behind it on Monday, calling it case closed, even as the breach provoked bipartisan criticism and opened up divisions inside the White House.

White House press secretary Karoline Leavitt said Monday that national security adviser Mike Waltz continues to have President Donald Trump’s confidence and that it was done discussing the embarrassing matter of senior officials communicating about plans for an airstrike on a commercial messaging app.
