Former President Bill Clinton visited with his predecessor, former President George H.W. Bush, and his wife Barbara at their home in Houston on Sunday (April 9th). Clinton tweeted about the visit, saying he and the Bushes, quote, "caught up about kids, grandkids, old times and new times. And socks." He included a picture showing him giving colorful socks to the 92-year-old former president, who is known for wearing whimsical socks, which show on his ankles since he uses a wheelchair because he has a form of Parkinson's disease.
