On Sunday, Veterans for Common Sense, a Washington, D.C., veterans' advocacy group, issued a statement in support of Olsen.
"Veterans for Common Sense is troubled to learn that Iraq War veteran Scott Olsen was badly injured this week by police at the Occupy Oakland gathering. We wish him a speedy and full recovery. VCS supports the right of Veterans for Peace to exercise the freedoms they have defended with their service."
Last Thursday, the Iraq and Afghanistan Veterans of America, a prominent, nonpartisan veterans advocacy group, called for a full and complete investigation into Olsen's injuries.
"The injury of any veteran is a serious concern to the broader veterans community -- especially when it happens on American soil. Scott Olsen and his family are in our thoughts and prayers, and we hope for his speedy recovery," the statement said.
While not every veteran in support of Olsen necessarily supports the Occupy Wall Street movement, those like Olsen and Thomas are participating because they believe in the cause.
"I'm doing this because I believe it is the right thing to do," Jenkins said. "And if we lose at least I will feel good about having done my best to stand up for what I believe is in the best interest of current and future generations of not only my country but the world."
