Schiff launches campaign for Feinstein's California Senate seat, setting up epic Democrat primary

California Rep. Adam Schiff on Thursday launched his 2024 campaign for Senate, possibly setting up a Democratic primary challenge against incumbent Sen. Dianne Feinstein. 

"When a dangerous demagogue tried to undermine our democracy, I wasn't about to let him," Schiff says in a voice-over in his first campaign ad as videos of former President Donald Trump play.

Schiff, who has served in Congress since 2001, was one of the lead investigators in Trump's first impeachment inquiry and a lead impeachment manager for the former president's second impeachment.

The 89-year-old Feinstein has not said whether she plans to run for reelection.

Schiff may also face off in the primary against Democratic Rep. Katie Porter, who launched her bid earlier this month.
