Jenna Bush Hager interviewed her grandfather George H.W. Bush about his decision to shave his head in support of little Patrick Friday on MSNBC.
Patrick, who's last name cannot be identified for security purposes, is the two-year-old son of one of President H.W. Bush's Secret Service detail who is undergoing treatment for leukemia.
G.H.W. Bush and members of his security team have all shaved their heads in solidarity with Patrick.
The issue is personal for the former president and first lady Barbara Bush, who lost their daughter Robin to leukemia almost 60 years ago.
