First lady Hillary Rodham Clinton, first cat Socks and Santa Claus (Secret Service agent Jim Shea) give out teddy bears during their visit to Children's National Medical Center in Washington Friday. Hillary Clinton met privately with children in the hospital's cancer ward, then helped lead the festivities in the atrium, singing Christmas carols and receiving presents for her family. The children got a chance to ask her questions ranging from whether Santa Claus comes to the White House - she said he did last year - to whether Socks gets presents - absolutely.
