Openly gay House members Jared Polis of Colorado, David Cicilline of Rhode Island and Tammy Baldwin of Wisconsin are cheering President Obama's gay marriage nod.

On Wednesday, Obama became the first sitting president to endorse gay marriage.

Appearing on MSNBC's The Daily Rundown, Baldwin, who could become America's first openly gay senator, said she was moved by the president's endorsement.

“I was really moved when I watched the interview with the president,” Baldwin told host Chuck Todd. “I thought it was [a] very heartfelt statement that the president issued about his own personal journey. And I think it's a journey shared by so many Americans as they grapple with this issue. I applaud the president and I think it was a very important statement yesterday.”

Polis tweeted a thank you: “Thank you @BarackObama for supporting marriage equality for all Americans.”

Cicilline messaged “President Obama took bold step of recognizing same-sex couples in committed relationships entitled to the same rights as every American!” and “The President's move represents true progress for our country and I salute his leadership.”

Massachusetts Congressman Barney Frank, who is preparing to marry his partner Jim Ready in July before he leaves Congress, said Obama's endorsement “will cost him no votes.”
