We hope you didn't drive to work today. Presumptive Democratic presidential nominee Hillary Clinton is currently holding a luncheon in San Francisco—and traffic is going to be baaad.

The fundraising luncheon, which starts at 11 a.m., will feature special guests including actress Jaime Lee Curtis and Planned Parenthood president Cecile Richards. Tickets ranged between $500 and $27,000.

UPDATE: According to various tweets, it looks like the fundraiser is being held at the Nob Hill Masonic Center.

The luncheon marks Clinton's first visit to the Bay Area since campaigning prior to California's primary elections earlier this month. Meanwhile, Donald Trump is on the campaign trail in Maine.
