Protesters affiliated with the Occupy Wall Street movement say they have filed paperwork with the National Park Service seeking permission to demonstrate on the National Mall on Jan. 17 in an event billed by the group as “Occupy Congress.” However, a spokeswoman for the National Park Service said that they had not yet received the application.

The application was posted online Tuesday by applicants listed as “Occupy Congress and Occupy DC,” and with McPherson Square listed as as the applicant’s address. “Peaceful 1st Amendment demonstrations, including holding signs and group speaking”is the stated purpose.

About 50 Occupy D.C. protesters joined activists from around the country on Capitol Hill in a “Take Back the Capitol” event Dec. 6. Occupy D.C. organizers are hoping for at least 2,000 marchers to arrive from around the country for “Occupy Congress,” according to The Examiner’s Aubrey Whelan.

Whether or not the group’s permit is approved may be irrelevant; protesters living in the McPherson Square encampment since early October have never had a permit to stay. A separate group of protesters, affiliated with “Stop the Machine,” received a four-month extension to their permit to camp at Freedom Plaza in early October, according to protest organizer Margaret Flowers. That permit is set to expire Friday at 10 p.m.

Freedom Plaza protesters have received an extension on their permit through Feb. 28; they’ll have to share space with counter-protesters from Feb. 12 through March 15, according to The Post’s Annie Gowen.

“Submitted. . . . approved or not we’re coming. This will just make it easier to provide some basic necessities and structure to this event,” read an update posted to the “Occupy Congress January 17, 2012” Facebook page.
