A planned immigration reform rally will take place on the National Mall on Tuesday even though the site is closed due to the government shutdown.

Organizers for the " Camino Americano: March for Immigration Reform" were spotted Monday setting up a stage and equipment on the National Mall for the rally which will take place on Tuesday.

A few scattered barriers around the park have signs informing visitors that the area is closed as a result of the government shutdown.

Susana Flores, a spokesperson for the rally, confirmed for the Washington Examiner that the Park Service will allow the event to take place under the group's rights granted by the First Amendment.

About 30 members of Congress are expected to attend the rally, including House Minority Leader Nancy Pelosi, D-Calif., and Sen. Robert Menendez, D-N.J.

The event is hosted by several immigration activist groups, together with the Service Employees International Union ( SEIU) and the AFL-CIO.
