iStock/Thinkstock(WASHINGTON) — A top House Republican is criticizing President Trump’s national security adviser for declining to clarify the White House position on the location of the Western Wall.

H.R. McMaster, in a press briefing Tuesday previewing Trump’s first foreign trip, declined to elaborate on the location of Judaism’s holiest site after reports that a U.S. official told Israeli counterparts the wall was located in the West Bank.

“That sounds like a policy decision,” he said to reporters.

Rep. Mark Meadows, R-N.C., a leader of the conservative House Freedom Caucus, called McMaster’s lack of clarification a “concerning shift” in the administration’s policy.

“There is no question that both geographically and historically the Western Wall has been part of the state of Israel,” he said in a statement.

“As one of Israel’s closest allies, the United States has an obligation to stand by them and defend their rightful claim to one of the holiest sites in the nation of Israel. I hope H.R. McMaster will retract his remarks swiftly,” he added.

A senior Israeli official in Prime Minister Benjamin Netanyahu’s office confirmed to ABC News that Israel has asked the United States to clarify its position on the Western Wall after a “senior member of the U.S. delegation” prepping for Trump’s upcoming visit told his Israeli counterparts that the Western Wall is “not your territory. It’s part of the West Bank.”

Israel’s Channel 2 reported this exchange occurred after the Trump team rejected a request for Netanyahu to accompany Trump on his visit to the Western Wall, becoming the first sitting U.S. president to do so.

“The view that the Western Wall is part of the West Bank was received with shock,” the official said.
