Who is Mike Waltz? All about Trump's security adviser who took "full responsibility" for Signal group chat scandal and called Jeffrey Goldberg a 'loser'

As per Donny, the Signal group chat fiasco is no biggie!
The Atlantic's editor-in-chief, Jeffrey Goldberg, claimed on Monday that he was inadvertently added to a private Signal chat group used by senior officials in the Trump administration. The group, named "Houthi PC small group," discussed classified military plans, including imminent US strikes on Yemen. The revelation raises serious concerns about the administration’s handling of sensitive national security communications.
While US Defense Secretary Pete Hegseth and other senior national security officials admitted in an unsecured group chat used to coordinate airstrikes against Houthi targets in Yemen last month to include Goldberg in their group chat without his knowledge, which appears to have violated several federal rules and standards, President Trump claimed there "was no classified information as I understand it," when he was peppered with questions on the reported mishap during a meeting with his ambassadors at the White House. He added, "They used an app, if you want to call it an app, that a lot of people use. A lot of people in government use, a lot of people in the media use,” downplaying the whole fiasco.

Although the US President came to the defense of national security adviser Michael Waltz and touted the military operation as a success, Waltz announced on Tuesday that he takes "full responsibility" for the scandal involving the use of an unclassified commercial chat app to discuss plans to strike Yemen by senior officials.

Waltz said in an interview on FOX News’ ‘The Ingraham Angle’, "A staffer wasn't responsible. I take full responsibility. I built the group ... my job is to make sure everything's coordinated." He added, "We made a mistake and lessons learned. ... We're not using Signal app anymore."
When asked how Goldberg's number was added to the chat, Waltz said, "Have you ever had somebody's contact that shows their name ... and then you have somebody else's number there?"

Quoting Goldberg, the veteran journalist as a ‘loser’, Waltz said, "So, of course, I didn't see this loser in the group. It looked like someone else. Now, whether he did it deliberately or it happened in some other technical means is something we're trying to figure out."
