Rep. Barbara Lee (D-Calif.) is in contact with the family of Iraqi war veteran Scott Olsen, an Occupy Oakland protester who was injured Tuesday night, reportedly due to police action, and has offered assistance to Olsen, Lee’s office said Friday.

Olsen, 24, was struck in the head during an incident involving the Oakland police at a demonstration against Wall Street in front of Oakland City Hall. Olsen, currently in Oakland's Highland Hospital, has become a rallying point for the nationwide Occupy Wall Street protest movement.

“I shared my outrage and grave concern about the police brutality in Oakland directly with the Mayor,” Lee said Thursday in a news release. “My thoughts go out to the injured and especially Scott Olsen. I strongly support the occupy movement and continue to stand with the peaceful protesters in this struggle for economic justice and equality.” 

Lee, who represents Oakland, told MSNBC on Friday that she is also calling for an outside investigation into allegations of police brutality.

According to the nonprofit organization Iraq Veterans Against the War, Olsen is a former Marine who served two tours of duty in Iraq.

“Scott is one of an increasing number of war veterans who are participating in America’s growing Occupy movement,” IVAW said.

Olsen is a member of the group, which has accused police of throwing the projectile that hit Olsen in the face, fracturing his skull. According to the Occupy Wall Street website, Olsen was hit at close range.

As of Friday, Olsen’s condition had been upgraded to fair from critical. He remains in intensive care. According to published reports, he may require surgery to relieve the swelling to the brain.

Oakland Mayor Jean Quan and Police Chief Howard Jordan held a news conference Wednesday regarding the incident. Jordan said that to his knowledge, Oakland police did not use rubber bullets, wooden dowels or flash-bang grenades in removing protesters from City Hall, although they did use tear gas in the form of gas balls rolled on the ground.

Quan decided to reopen the plaza in front of City Hall to protesters on Thursday, after having signed off on the plan to remove them by Tuesday — a decision that some say sparked the violence.

Liberal activist group released a video Thursday blasting Quan for the way she handled the crisis.

“Mayor Quan, is this your city? Is this how we treat free speech in the United States of America?” the ad questions in a voice-over.

The Oakland police department issued a statement Tuesday saying protesters who had been ordered to disperse “began throwing paint or other hazardous material at the officers who deployed gas as a defense tactic.”

But Lee said there was no excuse for police to respond the way they did.

“The reaction was not appropriate,” Lee said Friday on MSNBC. “These are peaceful protesters who have a right to petition their government.”
