Actress Cynthia Nixon considers primary challenge to NY Gov. Andrew Cuomo

It would be her first bid at political office for the longtime activist.

"Many concerned New Yorkers have been encouraging Cynthia to run for office, and as she has said previously, she will continue to explore it. If and when such a decision is made, Cynthia will be sure to make her plans public," Rebecca Sides Capellan said in a statement.

The actress is a longtime ally of the mayor. Nixon's wife, Christine Marinoni, works in de Blasio's administration as a special adviser for community partnerships in the Department of Education.

The gubernatorial primary is Sept. 13 and the filing deadline is July 12.
