President Donald Trump on Tuesday morning said he still supports National Security Advisor Mike Waltz, after military plans were disclosed on a messaging app with The Atlantic's editor-in-chief.

"Michael Waltz has learned a lesson, and he’s a good man," Trump said during a phone call with NBC News.

Trump’s senior national security officials accidentally shared sensitive details about strike plans on the Houthi terrorist group in Yemen with editor-in-chief Jeffrey Goldberg through the encrypted messaging app Signal. 

The messages between Defense Secretary Pete Hegseth, Waltz and Vice President JD Vance and 15 other senior officials involved discussions in the lead up to the strikes carried out against the Iran-backed Houthi terrorist group in Yemen last week and raises questions about the use of the private messaging app for conducting government business.
