Trump suggesting Iran strike LA and San Diego at a rally signals major geopolitical volatility.
Context
What happened: At a Nebraska campaign rally, President Trump appeared to suggest letting Iran "take out" Los Angeles and San Diego. Gov. Gavin Newsom and California officials condemned the remarks.
Why it matters: Newsom said he is directing the State Threat Assessment Center to monitor the situation, and called for Trump's removal under the 25th Amendment. The White House said his words were misinterpreted.
Key numbers: LA is the second-most populous U.S. city; San Diego is the eighth-largest. Camp Pendleton hosts 70,000 civilians and active-duty service members.
