The race to the White House is coming through San Diego.

On Friday, U.S. Senator and candidate for the Democratic nomination, Bernie Sanders will hold a campaign rally in San Ysidro.

Sanders will be speaking at an immigration rally at the San Ysidro Athletic Quad on 5353 Airway Rd.

Doors open at 4:30 p.m. and it is free to the public, but the campaign recommends anyone interested in attending the rally should RSVP online.

Sanders visited San Diego in March when he held a rally at Waterfront Park.

The two-time presidential hopeful will kick off his latest tour of Southern California with a rally in the Coachella Valley on Monday night, before heading to a town hall in Moreno Valley, ending with his forum in San Ysidro.

The campaign says Sanders has a lot of support in the Golden State.

"[Bernie 2020] has surpassed 8 million attempted voter contacts, opened five offices, held more than 4,300 events, and more than 760,000 people have taken action with the campaign," reads a statement from Anna Bahr, the California spokesperson for the campaign.

Sanders challenged Hillary Clinton in the 2016 Democratic primary, but lost. During that campaign he held a rally in National City that city officials said the campaign was slow to pay.

The city said it received the payment in Oct. 2017, almost a year-and-a-half after the rally in 2016.
