George H.W. Bush wore socks with books on them to Barbara Bush's funeral
Former president George H. W. Bush honored his late wife by wearing socks with books on them to her funeral Saturday.
Barbara Bush championed the issue of literacy throughout her life and her husband has a reputation for wearing colorful socks.
"To honor his wife of 73 years and her commitment to family literacy, for which she raised over $110 million over the course of over 30 years, @GeorgeHWBush will be wearing a pair of socks festooned with books at today’s funeral service for former First Lady Barbara Bush," tweeted the couple's spokesman Jim McGrath.
The former first lady, who died Tuesday at 92, formed the Barbara Bush Foundation for Family Literacy to fund programs that teach parents in low-income families to read and pass on reading to their children.
"If everyone could read and write, all the problems I worried about could be solved," she told USA TODAY in 2014. "If you can't read, you can't do anything."
McGrath later tweeted a photo of the socks worn by the 93-year-old.
