House Democrats will host a fundraiser toasting the 25th anniversary of Massachusetts Rep. Barney Frank's coming out gay.

The 72-year-old Frank came out in 1987 at the age of 47, becoming the first member of Congress to voluntarily announce his sexual orientation. He is currently one of four openly gay House members, including Representatives Tammy Baldwin of Wisconsin, Jared Polis of Colorado and David Cicilline of Rhode Island.

According to The Hill, the reception will take place next Wednesday on the rooftop of El Centro DF restaurant and is being hosted by House Minority Leader Nancy Pelosi and Democratic Congressional Campaign Committee (DCCC) Chairman Steve Israel.

“Barney is an inspiration to all of us as one of the first openly gay congressmen to serve in the House,” wrote Polis in an email announcing the reception. “This event will be particularly moving for me as it will be one of the last events with him before he retires this year.”

Tickets range from $100 for an individual to $5,000 for PACs and co-hosts.

Frank announce in November that he would not run for reelection after serving 16 terms. He and long-time partner Jim Ready will marry in July in Massachusetts.
