House Minority Leader Nancy Pelosi on Tuesday called on the National Park Service to cancel an alt-right rally slated to take place in a park near San Francisco's Golden Gate bridge at the end of the month.

"I am deeply alarmed by the hateful and dangerous nature of the event, its timing so soon after the horrors in Charlottesville, and the serious questions over whether the National Park Service is at all equipped to ensure public safety during a white supremacist rally," said Pelosi, D-Calif., who represents San Francisco. "The NPS should reevaluate its decision and its capacity to protect the public during such a toxic rally."

A group called Patriot Prayer has scheduled a free speech rally on Aug. 26 at San Francisco's Crissy Field. The National Park Service has issued a permit for the event, but Pelosi wants them to revoke it.

"We must wonder, where is the decision to permit a white supremacist rally in a national park being made?" Pelosi said in the statement. "At the National Park Service? In the Department of the Interior? Or under guidance from the White House? Perhaps those making the decision did not know that Crissy Field is a place where families gather, where tourists visit, and the community comes together. Free speech does not grant the right to yell fire in a crowded theater, incite violence or endanger the public in any venue."

A Facebook page described the event as "a day of freedom, spirituality, unity, peace, and patriotism," featuring a live musical performance by Good Ol' Boyz.

"San Francisco has long been a city that prides itself in acceptance of all, so together, let's unite in this beautiful city to listen to some great speakers & live music!" organizer Joey Gibson wrote on Facebook.
