A new 30-second ad released Wednesday features President Barack Obama and former Vice President Dick Cheney making the case for gay marriage.

The $1 million ad campaign is being paid for by the Respect for Marriage Coalition, which is co-chaired by the Human Rights Campaign (HRC), the nation's largest gay rights advocate.

In the ad, which will air on national cable, former first lady Laura Bush is heard telling CNN's Larry King, “When couples are committed to each other and love each other, then they ought to have the same sort of rights that everyone has.”

Former Secretary of State Colin Powell also makes an appearance.

The video ends with footage of Obama's inaugural address last month.

“Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law,” Obama said. (The video is embedded on this page. Visit our video library for more videos.)

According to the Respect for Marriage Coalition, it is the first time in history that LGBT rights groups have funded a national ad buy.

“Against the backdrop of President Obama's historic comments about marriage rights in his inaugural address, freedom to marry legislation pending in a number of states, and two landmark marriage cases before the U.S. Supreme Court, the Coalition is working to grow support for marriage rights for same-sex couples across the nation,” the group said in a statement.
