Sen. Chuck Schumer used the occasion of Sunday’s NYC Pride March to announce that his daughter, Alison, will be marrying her fiancée, Elizabeth Weiland. The women plan to walk down the aisle on Nov. 18.

“Marching in the #NYCPride Parade has special meaning this year as I am marching with my daughter Alison and her wonderful fiancée Biz! #HappyPride,” tweeted the politician, who wore a lavender shirt to the pride parade.

Alison, 29, is an executive at Facebook, while Weiland’s LinkedIn page says she is in her second year of an MBA program at Columbia University.
