After a group of veterans broke down the barricades at the national World War II Memorial Tuesday afternoon, organizers of one Hero Flight Network group told BuzzFeed it wasn’t the last Washington would hear from them. Veterans are plotting another protest at the same place Wednesday, and expressed interest in staging similar events at sites across the nation’s capital, including the Lincoln Memorial — an act of civil disobedience that would likely pour fuel on the already highly flammable politics of the government shutdown.

“We have people here that are 80 and 90 years old and they closed down all the bathrooms?” said Tony Nussbaum, a 25-year veteran of the Air Force from Iowa and a leader of the state’s Hero Flight group. “I’m about to just start pissing on the trees.” …

On Wednesday, the scene could repeat itself when groups from the Honor Flight Network — a national charity that brings aging World War II veterans to visit the national monument to the conflict they fought in — are scheduled to arrive at the massive outdoor memorial. Meanwhile, veterans have pondered staging a similar protest at the Lincoln memorial, said Jamie Miller, a five-year veteran of the Marine Corps and another organizer of the Iowa group that stormed the World War II memorial Tuesday.
