George W. Bush turns 70

Former president George W. Bush hit the big 7-0 on Wednesday, and he's celebrating with a bike ride alongside Wounded Warriors.

Bush's daughter, Jenna Bush Hager, tweeted a photo of the former president cycling along a trail.

The photo was originally posted on Bush's Instagram account.

Bush isn't the only former president turning 70 this summer. Bill Clinton, his immediate predecessor, turns 70 next month. Meanwhile, the potential 45th president, Donald Trump, hit that milestone in June.
