Hillary Rodham Clinton will receive the 2013 Liberty Medal at the National Constitution Center in Philadelphia.
Jeb Bush, the chairman of the Constitution Center, will present the award to Clinton at a ceremony scheduled for Sept. 10.
Both Clinton and Bush are potential contenders in the 2016 presidential elections, for opposing parties. But in a statement, the GOP's Bush only accentuated the positive.
"Former Secretary Clinton has dedicated her life to serving and engaging people across the world in democracy," said Bush, the Republican former Governor of Florida, son of a former president and brother of another. "These efforts as a citizen, an activist, and a leader have earned Secretary Clinton this year's Liberty Medal."
Tickets for the general public will be made available in August. Details will be released next month, a Constitution Center spokeswoman said.
The Liberty Medal was established in 1988 to commemorate the bicentennial of the U.S. Constitution. Previous recipients include former Presidents George H.W. Bush and Bill Clinton, U2 frontman Bono, filmmaker Steven Spielberg and Nelson Mandela.
