Katie Vacanti-Mitchell, far left, met President George Bush at the White House on Wednesday as part of the Children's Miracle Network's Champions Across America program. Katie, 13, has leukemia and was chosen to represent Tennessee as a child champion because of a fund she started to help other cancer patients at the Monroe Carell Jr. Children's Hospital at Vanderbilt. She recently returned from a week-long trip to Walt Disney World in Orlando, Fla., and Washington, D.C.
