President Joe Biden spent part of Thursday morning touring an L.A. Metro construction site, just one stop on his two day visit to Los Angeles.

“We expect to see nearly 80,000 more riders on the Metro every day, thanks to the Purple Line extension,” Biden said at the event. “It’s going to effect pollution in a significant, positive way.”

The president is also expected to attend a fundraiser Thursday night for Congressional Democrats.

The fundraiser will be one of many the president has headlined this year for the Democratic National Committee which have collectively brought in more than $20 million, the Associated Press reported.

Motorists on L.A.’s West Side can expect motorcade closures between 2 p.m. and 6 p.m., the Patch reported.

The president will finish his trip to Southern California in Orange County for a speech about inflation.

The trip comes amid the unwelcome backdrop of rising gas prices. Californians are currently paying the highest prices in the nation.

Biden will travel to Orange County on Friday.
