Former Sen. Barbara Boxer assaulted and robbed

Former U.S. Sen. Barbara Boxer was assaulted and robbed in Oakland Monday afternoon, her representatives tweeted.

"The assailant pushed her in the back, stole her cell phone and jumped in a waiting car. She is thankful that she was not seriously injured," the tweet read.

The Oakland Police Department said in a statement to ABC News that it is investigating the incident, which took place around 1:15 p.m.

"The suspect forcefully took loss from the victim, and fled in a nearby waiting vehicle," the police said in a statement.

A representative for Oakland Mayor Libby Schaaf told ABC News in a statement that the police are working on collecting any surveillance images from the area where the incident took place.

"[Schaaf] spoke with the Senator’s family to extend her well wishes for a speedy recovery and was relieved to learn she was not seriously injured," spokesman Justin Berton said in a statement.

Boxer, 80, served as California's U.S. Senate representative from 1993 to 2017. She also served in the House of Representatives for a decade.
