Caroline Kennedy: "I Do" to Marriage

Caroline Kennedy has become the 100,000th signer of Freedom to Marry's open letter to President Barack Obama -- part of the group's "Say, 'I Do'" campaign urging the president to fully embrace marriage equality.

"Falling in love, getting married, and building a family is part of the American dream," Kennedy said in a statement. "I believe that all Americans, including committed gay and lesbian couples, should have the opportunity to pursue that dream."

Freedom to Marry political director Sean Eldridge said Kennedy is part of a "growing chorus of voices ... calling on the President to complete his journey and join the majority of Americans who support the freedom to marry."
