lmLisa Murkowski, the Republican senator from Alaska, joins Rob Portman of Ohio and Mark Kirk of Illinois, to become the third Republican senator to back marriage equality:

Today Senator Lisa Murkowski (R-AK) announced that she supports marriage equality. Murkowski joins two of her Republican colleagues – Senator Rob Portman of Ohio and Senator Mark Kirk of Illinois – in endorsing the right of committed and loving gay and lesbian couples to marry. Human Rights Campaign (HRC) President Chad Griffin released the following statement in response to the news:

“Senator Murkowski’s courageous and principled announcement today sends a clear message that marriage equality must come to all 50 states in this country. As the Supreme Court prepares to rule in two landmark marriage cases this month, a growing bipartisan coalition is standing up for the right of all couples to marry—and there is no turning back that tide. We hope other fair-minded conservatives like Senator Murkowski stand up and join her. Alaska may be nicknamed ‘the Last Frontier,’ but we’ve got to make sure that LGBT Alaskans don’t have to wait to find justice.”

Fantastic.
