Obama: Undeniable Shift in Attitudes on Gay Marriage

WASHINGTON -- President Barack Obama says regardless of how the Supreme Court rules in an upcoming decision on gay marriage, there has been an undeniable shift in attitudes across the country.

Obama spoke at a gay pride month reception at the White House. He says he is closely watching the decisions the high court will announce in the coming days, which include a case that could affirm the right of gay couples nationwide to marry.

The president singled out discrimination facing transgender Americans as an area where more progress needs to be made.

Obama's remarks were interrupted by a heckler protesting the detention and deportation of gay, lesbian and transgender immigrants. The president sharply rebuked the protester, saying it was "not respectful" to interrupt someone after being invited to their house.
