Macungie Mayor Shares Obama's Views on Same-Sex Marriage

President Barack Obama has publicly come out in support of gay marriage, the first time in history that a sitting U.S. President has ever done so. 

Obama gave the news to ABC News' Robin Roberts in an interview that will air on ABC's “Good Morning America" on Thursday.

"I have to tell you that over the course of several years as I have talked to friends and family and neighbors when I think about members of my own staff who are in incredibly committed monogamous relationships, same-sex relationships, who are raising kids together, when I think about those soldiers or airmen or marines or sailors who are out there fighting on my behalf and yet feel constrained, even now that Don't Ask Don't Tell is gone, because they are not able to commit themselves in a marriage, at a certain point I’ve just concluded that for me personally it is important for me to go ahead and affirm that I think same sex couples should be able to get married,” Obama told Roberts.

The news comes just days after Vice President Joe Biden said he supports gay marriage.

Macungie Mayor Rick Hoffman months ago, on Valentine's Day.

Hoffman said he is "Proud to be a part of this national effort to win equal rights for everyone.”

"If two consenting adults want to marry, who are we to tell them no?" he said.

Hoffman is one of six Pennsylvania mayors -- out of thousands -- who have declared their support. The others include the mayors of Bethlehem, Easton, Reading, Doylestown and Philadelphia.
