Former Presidents George W. Bush and Bill Clinton are speaking this evening about leadership at the 2017 Presidential Leadership Scholars graduation. The discussion is moderated by David Rubenstein.

Bush has previously described Clinton as being his "brother from another mother."

He later admitted that the reason he began painting was "because I was bored." At the time he was reading a biography by Winston Churchill who also painted. "I decided if that guy could paint so could I."

Clinton admitted that the reason he began the foundation after his presidency was that he couldn't paint and "I'm a work-a-holic."

He also noted that when he first saw Bush's speech "in a tent sittin' on a bail of hay" campaigning at the Iowa Caucus, he called former Vice President Al Gore and warned him that Bush could win because he was able to speak to everyday Americans. Clinton recalled seeing "my good friend" Ann Richards, who he said had a 60 percent approval at the time, in Texas the governor's race. He warned Democrats not to underestimate Bush.

Bush warned that the one thing people need to understand if they're running for office is to "know what they don't know" and be willing to listen to those who are smarter than them.

Clinton warned that running for office isn't about "you," rather it's about Americans.
