Vice President Joe Biden will help Freedom to Marry celebrate the recent Supreme Court ruling striking down gay marriage bans in all 50 states during an event Thursday on Wall Street.

The event will “celebrate success in winning marriage nationwide and the triumph it represents for America,” the group said.

Biden announced his support for marriage equality during a 2012 appearance on NBC's Meet the Press. Within days, President Barack Obama announced that he had “evolved” on the issue and now supports allowing gay couples to marry.

Last year, Biden said that his comments were not planned.

“I want you to know, to set the record straight, my comments on Meet the Press were not planned,” Biden told a NetRoots Nation audience. “I get asked a direct question, I give a direct answer. I come out of the civil rights movement, and there's no way in God's green Earth that I can sit there and be asked a question about the civil rights issue of our day and remain silent. It would have made a lie of who I am.”

This will be one of the few appearances Biden has made since his son, Beau Biden, died of brain cancer in May.
