Former President George H.W. Bush, 89, sported a clean-shaven head in solidarity with a 2-year-old named Patrick, who lost his hair when he started being treated for leukemia.

The 41st president was pictured in a wheelchair today on the family's Maine compound sporting his signature colorful socks, with Patrick seated on his lap. Both he and Patrick wore light-blue shirts, although Patrick had a couple of toy cars, as well.

Patrick is the son of, Jon, a member of Bush's Secret Service detail, many of whom also went under the razor to support the young cancer fighter. (Last names were withheld at the request of the family, Bush's office said)

Bush and Barbara Bush have an even more personal connection to Patrick's fight. They lost their second child, Robin, to leukemia 60 years ago when she was 4.

Members of the Bush Protective Detail have set up a website, www.patrickspals.org, to help pay for Patrick's medical bills. And they have organized the Inaugural Patrick's Pals Motorcycle Benefit Run in Kennebunkport, Maine, to help pay for Patrick's treatments.
