Sen. Ted Cruz, R-Texas; Sen. Mike Lee, R-Utah; and former Alaska governor Sarah Palin joined veterans at the National Mall in Washington, D.C., on Sunday to protest the closures of open-air monuments such as the World War II memorial.

"Our veterans should be above politics," Cruz said during an interview with Fox News at the World War II memorial. "It is shameful that the administration is barricading and trying to shut down the memorials."

Cruz pointed out that the House of Representatives voted to fund and open the national memorials, but that Senate Democrats refused to pass it.

"This belongs to the people," Lee explained. "We are here to show our solidarity with them and this is not a tool to be used against them in a political fight. This is theirs."

Palin explained that she was also there to show solidarity with American veterans.

"We think it's atrocious that our military is being used as political pawns in a political game, and we're going to change that," she said.

The group of veterans picked up several barricades at the World War II memorial and carried them to the White House, throwing them into a pile.
