Overview

• President Trump removed Mike Waltz as National Security Adviser following a security breach and policy disagreements, nominating him as UN ambassador.
• Secretary of State Marco Rubio is temporarily serving as acting National Security Adviser, a dual role last held by Henry Kissinger in the 1970s.
• Waltz's ouster stemmed from the 'Signalgate' scandal, where a journalist was mistakenly included in a sensitive military group chat, and his coordination with Israel on potential strikes against Iran without Trump’s approval.
• Democrats, including Senators Tammy Duckworth and Mark Warner, predict a challenging confirmation process for Waltz, citing security concerns and his handling of classified information.
• President Trump has suggested Stephen Miller as a leading contender to permanently replace Waltz as National Security Adviser, with a decision expected within six months.
