Sen. Bernie Sanders is projected to win the California Democratic primary, the crown jewel of Super Tuesday with 415 delegates at stake, according to AP.

The big picture: Sanders was heavily favored to win California, despite losing in the 2016 primary to Hillary Clinton by about 7 points. Super Tuesday was largely dominated up until the California results by Joe Biden, who won sweeping victories across the South.

  • California is also a key state for mapping Latino support, which are a core part of Sanders' base.

Spending by candidates in the state was sporadic. Per NPR, Sanders spent about $7 million on ads in California. Former Vice President Joe Biden, however, bought no television ads and spent just $4,000 on digital ads.

  • But Biden likely received a late boost from Sen. Amy Klobuchar and former South Bend, Ind., Mayor Pete Buttigieg, moderates who suspended their campaigns and endorsed him just before Super Tuesday.

Former Mayor Michael Bloomberg spent a whopping $71 million on ads in the state.

Secretary of State Mike Pompeo told Fox News' Laura Ingraham on Monday that the Trump administration is "looking at" a ban on Chinese social media app TikTok.

Why it matters: Lawmakers have long expressed fears that the Chinese government could use TikTok to harvest reams of data from Americans — and actions against the app have recently accelerated worldwide, highlighted by India's ban.
