Link: George H.W. Bush shaves head for 2-year-old cancer patient - CBS NewsFormer President George H.W. Bush shaved his head on Tuesday, supporting a two-year-old with leukemia whose father is part of the 89-year-old's Secret Service detail.
Members of the Bush Protective Division began removing their hair last week in solidarity with Patrick, who was diagnosed with leukemia last spring, Bush's spokesperson Jim McGrath told CBSNews.com.
Bush said "it was very easy for him to do," McGrath said.
Patrick's prognosis is "good," but his treatment and illness carry a special place in Bush's heart as his daughter Robin died of the same blood disease in 1953 when she was three.
His Secret Service members have organized a website and 50-mile motorcycle ride through Maine - where Bush resides - to help pay for Patrick's medical bills.
