Gov. Chris Gregoire, D-Wash.
"Thank you Mr. President. Along with thousands of Washingtonians who stand strongly for marriage equality, today we thank you for your courageous and heartfelt act. As we know in Washington state, families are families and we cannot deny equal rights to committed, loving couples. Passing the marriage equality bill was among my proudest accomplishments. Today I'm equally proud of our President."
WA State Sen. Ed Murray, D-Seattle
"In a 17-year effort to pass marriage equality legislation in Washington state, I have been inspired by the thoughtfulness and compassion shown by people of all walks of life as they consider such a deeply personal issue.
"President Obama sincerely considered the real issues faced by loving, committed gay and lesbian couples and concluded that America's highest ideals are best served by justice, and justice is best served by true equality for us all, regardless of race, gender, religion or sexual orientation. I thank the president for his courage in taking a strong position in support of equality for all Americans. And I believe that, as more people come to know their gay and lesbian friends, family members and neighbors, as a state and a nation we will embrace marriage equality."
Rep. Jim McDermott, D-Wash.
"I applaud President Obama for making history today as the first sitting President to support full marriage equality. Without question his words today will shape the course of equality for generations to come. I am proud of the President for his courage in taking this historic step on the path of justice and equal rights - and I walk proudly with him to make our dream of equality a reality."
King County Executive Dow Constantine
"I commend President Obama for being on the right side of history in announcing his support for marriage equality today.
"Tomorrow we welcome President Obama to Seattle, and I will tell him how much we in King County appreciate his courage on this, the civil rights issue of our time.
"I am confident that the people of Washington will make ours the first state to recognize marriage equality by a public vote when we approve Referendum 74 in November."
House Minority Leader Nancy Pelosi, D-Calif.
"Today marks progress for the civil rights of LGBT Americans and all Americans. With President Obama's support, we look forward to the day when all American families are treated equally in the eyes of the law."
Republican National Committee Chairman Reince Priebus
"While President Obama has played politics on this issue, the Republican Party and our presumptive nominee Mitt Romney have been clear. We support maintaining marriage between one man and one woman and would oppose any attempts to change that."
