SAN FRANCISCO (KRON)—Hillary Clinton is scheduled to attend a campaign event in San Francisco Monday night via teleconference, according to a volunteer with her campaign.

Clinton was originally set to appear in person, but is not able to because she was recently diagnosed with pneumonia.

The event will be held at 4:30 p.m. at The Masonic on California St. It will have guest performances by k.d. lang and Liz Range.

Tickets to attend are between $250 to $50,000, according to the Clinton’s campaign website.

A video shows Clinton staggering and someone helping her into a car after the 9/11 memorial ceremony on Sunday.

The last time Clinton was in San Francisco was in June.
