Anti-war activist Cindy Sheehan is among the protesters gathering near the site where the George W. Bush Presidential Center will be dedicated.
She says she's protesting both Bush and his successor in the oval office.
Sheehan famously camped out near Bush's Crawford, Texas, ranch to protest the war in Iraq. Eight years after her son died in Iraq, Sheehan says she still has a reason to protest.
Sheehan feels that President Barack Obama has maintained much of Bush's national security strategy.
She says: "I wake up every day feeling like today's the day to make a difference. I never question the correctness of what I'm doing or the need for it."
