President says national security adviser Mike Waltz, suspected of adding journalist to chat, ‘has learned a lesson’

Donald Trump defended his embattled national security adviser on Tuesday and said the leak of highly classified military plans was “the only glitch in two months”, as scrutiny intensified into how top US officials shared operational details for bombing Yemen in a group chat.

In an interview with NBC, the president said, “Michael Waltz has learned a lesson, and he’s a good man,” as Democrats called for an investigation into the sharing of the plans for this month’s major airstrikes in Yemen on the Signal app. Later on Tuesday, during a meeting with ambassadors, Trump said his administration would investigate the incident but claimed “there was no classified information” shared on Signal.
