Who is Mike Waltz? What to know about Trump official who added reporter to Signal chat

After a journalist was added in a group chat containing a detailed plan for a U.S. strike on Iran-backed militants in Yemen, top Trump administration officials are under fire for the stunning security breach.
The Atlantic's editor-in-chief Jeffrey Goldberg reported in an article published Monday afternoon he was accidentally added to the Signal chat titled “Houthi PC small group” earlier this month by Mike Waltz, Trump's national security adviser. Other names in the group chat on the encrypted Signal app matched Vice President JD Vance, Secretary of State Marco Rubio and Director of National Intelligence Tulsi Gabbard.
Seemingly unaware the reporter was in the chat, the Trump officials plotted U.S. airstrikes on Iran-backed Houthi sites in Yemen that took place March 15. The conversations culminated with Hegseth, hours before the airstrikes, sharing secret plans ‒ including targets and attack sequencing ‒ in the chat, Goldberg reported.
While the White House has acknowledged the authenticity of the Signal chat, it downplayed the significance the significance of the breach, arguing the airstrike operation was executed as planned. White House press secretary Karoline Leavitt accused Goldberg of "sensationalist spin," insisting that no "war plans" were discussed.
Hegseth made the same claim to reporters Monday. "Nobody was texting war plans, and that’s all I have to say about that," he said.
