President Donald Trump on Tuesday downplayed the texting of sensitive plans for a military strike against Yemen's Houthis this month to a group chat that included a journalist, saying it was “the only glitch in two months” of his administration as Democratic lawmakers heaped criticism on the administration for handling highly sensitive information carelessly.

Trump said “turned out not to be a serious one," and expressed his continued support for national security adviser Mike Waltz.

Waltz, according to an article posted online Monday by The Atlantic, appeared to have mistakenly added the magazine's editor-in-chief, Jeffrey Goldberg, to a chat 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. He 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."
