Yesterday鈥檚 Trans Day of Action (TDOA) marked milestones for many in the LGBTQ+ community 鈥 including New York governor candidate Cynthia Nixon.

The Sex and the City star took to Instagram to honor her eldest of three children, Samuel Joseph Mozes, born Samantha Mozes, with a sweet post celebrating his accomplishments.

鈥淚鈥檓 so proud of my son Samuel Joseph Mozes (called Seph) who graduated this month,鈥 she wrote. 鈥淚 salute him and everyone else marking today鈥檚 Trans Day of Action,鈥 she wrote, adding the hashtag, 鈥淭DOA.鈥

TDOA is an annual march/rally that shines a spotlight on continued violence and discrimination in the transgender community. It was first organized by the Audre Lorde Project back in 2005.

The photo showcased mother and son posing together during graduation at Samuel鈥檚 alma mater, the University of Chicago.

Nixon, who is currently campaigning to be the first queer governor of New York, has long been a proponent for LGBTQ+ rights.

Back in May, she expertly clapped back at a jab made by former NYC Councilwoman Christine Quinn, who called the actress an 鈥渦nqualified lesbian,鈥 with a cheeky tweet that read as follows: 鈥淚t鈥檚 true that I never received my certificate from the Department of Lesbian Affaris, though in my defense, there鈥檚 a lot of paperwork that鈥檚 required.鈥

She also helped to set up Fight Back New York in 2010 in an effort to level the senate playing field by working to defeat those who opposed same-sex marriages.

As she herself said in 2017 speech on the subject, 鈥淎s LGBTQ+ people, we know how important coming out is. But I would argue that our coming out has never been more important than it is right now. Whether we are lesbian or gay or transgender Muslim or Mexican or any one of a number of other categories I could name, we are allies united by our otherness.鈥
