George HW Bush letter to Bill Clinton suggests there is some grace in politics

Washington (CNN)Hillary Clinton posted a letter on Instagram from former President George H.W. Bush to her husband welcoming former President Bill Clinton to the White House, amid increased questions about whether Donald Trump will accept the results of a November election.

"This is what leadership looks like," Clinton said Thursday on Instagram.

Bush did not win re-election in his 1992 presidential race against the former president but wished Clinton "good luck."

"I wish you great happiness here," Bush wrote on Jan 20, 1993.

"You will be our president when you read this note," he added. "I wish you well. I wish your family well."
