New York (CNN) Hillary Clinton marched in the New York Pride parade on Sunday, highlighting her support for same-sex marriage and national LGBT nondiscrimination laws.

Clinton, flanked by Secret Secret agents, stepped out of her motorcade near the Stonewall Inn, a gay bar in New York's Greenwich Village neighborhood that was recently named a national historic landmark because it was the site of 1969 riots for gay rights.

Clinton was joined by New York Gov. Andrew Cuomo and New York City Mayor Bill de Blasio. Actress Cynthia Nixon, known for her role on "Sex in the City," joined Clinton, as well.

Clinton marching four blocks of the parade route was a logistical nightmare for the New York Police Department and the Secret Service, who rarely left Clinton's side. Clinton, who seemed unfazed by the chaos, shook hands along the route and waved to the many well wishers.
