Barack Obama, Lady Gaga

The United States Senate voted to repeal the military's "don't ask, don't tell" policy Saturday, effectively allowing gay men and lesbians in the military to be open about their sexual orientation, according to The New York Times.

The law, which was passed in 1993 under President Bill Clinton's administration, was criticized by many for discriminating against homosexual troops. The repeal, which passed the Senate by a 65-31 vote, fulfills President Barack Obama's promise to reverse the ban.
