It was 25 years ago today (1 June) that Barney Frank became the first openly gay member of the US House of Representatives.
He talked with MSNBC's Laurence O'Donnell about the milestone and remembered a time when he was afraid that after coming out, people wouldn't vote for him.
Frank persevered and is retiring at the end of the current session after more than three decades in the U.S. House. During that time, he has seen a shift in the public's views on homosexuality.
