Paul Pelosi, 82, was booked into the Napa County Detention Center after being charged with two misdemeanours and bail was set at US$5,000, according to police and county online records. On Sunday, he was not listed as being in custody.

The California Highway Patrol said Pelosi was driving a 2021 Porsche and attempting to cross State Route-29, when his vehicle was struck by a 48-year-old man driving a 2014 Jeep. No one was injured, the highway patrol said. The other driver was not arrested.

California law bars drivers from operating a vehicle with a blood alcohol level above 0.08 grams per deciliter of blood.

Paul Pelosi could not immediately be reached for comment.

Nancy Pelosi was in Rhode Island on Sunday delivering a commencement address at Brown University.

Drew Hammill, her spokesperson, said: “The speaker will not be commenting on this private matter which occurred while she was on the East Coast.”

Nancy and Paul Pelosi have been married since 1963.
