“the only glitch in two months” of his administration as Democratic lawmakers heaped criticism on the administration for handling highly sensitive information carelessly.

Trump told NBC News that the lapse “turned out not to be a serious one”, and articulated his continued support for national security adviser Mike Waltz, who mistakenly added the editor-in-chief of The Atlantic, Jeffrey Goldberg, to the chain that included 18 senior administration officials discussing planning for the strike.

“Michael Waltz has learned a lesson, and he’s a good man,” Trump said in the NBC interview. The president also appeared to point blame on an unnamed Waltz aide for Goldberg being added to the chain. “It was one of Michael’s people on the phone. A staffer had his number on there.”

But the use of messaging app Signal to discuss a sensitive operation has opened the administration to blistering criticism from Democratic lawmakers who expressed outrage at the White House’s and senior administration officials’ insistence that no classified information was shared. Senior administration officials have struggled to explain why the publicly available app was used to discuss such a delicate matter. (Jamaica Gleaner/AP)
