There were also reports of voting machines malfunctioning.

Late Tuesday, Senator Bernie Sanders’s campaign filed an emergency motion asking a Los Angeles county judge to keep polling places open for an additional two hours on Tuesday night because of widespread reports of long lines and problems with voting machines, a spokeswoman for the campaign said.

The filing came after a steady stream of complaints throughout the county of faulty machines and two-hour waits in neighborhoods including Westwood, the San Fernando Valley, Los Feliz and the east side of Los Angeles.
