Who says Republicans and Democrats can't get along? Just ask Presidents George H.W. Bush and Bill Clinton.

42 paid 41 a visit Monday at his home in Kennebunkport, Maine.

"Luckily I had a freshly laundered pair of Bill Clinton socks to mark the occasion," Bush tweeted with a photo of his socks featuring Clinton.

The pair formed a close bond while raising millions for victims of natural disasters all over the world including Houston after Harvey, New Orleans after Katrina and Haiti after a devastating earthquake.
