(MSNBC) WASHINGTON — President Barack Obama honored a diverse cross-section of political and cultural icons — including former Secretary of State Madeleine Albright, astronaut John Glenn, basketball coach Pat Summitt and rock legend Bob Dylan — with the Medal of Freedom at a White House ceremony Tuesday.

“We could not be prouder of all of them,” Obama said as the ceremony concluded. “We could not be more grateful. You have had an impact on all of us and you will continue to have an impact on us.”

The Medal of Freedom is the nation’s highest civilian honor. It is presented to individuals who have made especially meritorious contributions to the national interests of the United States and world peace.
