LOS ANGELES — The statewide average price for a gallon of regular gasoline in California rose to an all-time high Monday, the third record-setting day in a row that is prompting calls for a federal investigation into the price spike.

The average price in the state hit $4.668, according to AAA. Sen. Dianne Feinstein, D-Calif., called on the Federal Trade Commission to investigate, saying residents need to be protected from “malicious trading schemes.”

In some locations, motorists paid $5 or more per gallon.
