On Sunday a bunch of WW2 vets arrived at the Iwo Jima memorial to find it "closed" and barricaded. It didn't really make the news, but the news was the vets 'stormed the barricades' and entered the memorial anyways!

UPDATE: I'm told, "The Syracuse Honor Flight just knocked down the barrier and a couple hundred of them are at the Memorial now."

then on Tuesday, the WW2 memorial barricaded but granted limited access, and on Wednesday the memorial was double barricaded and wired shut.

On Tuesday morning, seven National Park Service employees were seen erecting and tending to a barricade around the World War II memorial in Washington, D.C. One NPS employee was operating a forklift. There usually aren't any NPS employees working at the World War II memorial.
A couple hours later, when an Honor Flight of World War II veterans arrived, accompanied by Democratic and Republican members of Congress, the fences blocking the memorial were easily moved away, allowing the veterans to enter.
But the barriers are still at the memorial, and they've been reinforced. This morning, I walked by the memorial and noticed that wires had been used to tie the fences together:

On Wednesday, 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.
Park Service OKs immigration reform rally on 'closed' National Mall
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.
