Jonathan Bush, the younger brother of the late President George H.W. Bush and uncle of former President George W. Bush, has died. He was 89. Jonathan Bush died Wednesday at his home in Jupiter, Florida, according to a spokesman for the Texas-based George & Barbara Bush Foundation. He would have turned 90 on Thursday. In a post on Twitter, the foundation said he was “a fine gentleman and a noble soul," adding that he was “a great song and dance man — without a doubt the best dancer of his siblings.”
