Republican presidential front-runner Donald Trump says he’s “100 percent” on board with the remaining field of candidates in support of moving the U.S. Embassy from Tel Aviv to Jerusalem if elected president in the fall of 2016.

In an interview with The Brody File, published on Tuesday, Trump said “I am for that one hundred percent. We are for that one- hundred percent” when told by host David Brody that pledging to move the embassy to Jerusalem is a “tier-A issue for Evangelicals as it relates to support for Israel.”

Trump is currently tied for first place with Senator Ted Cruz in Iowa.

In December, Trump drew loud boos from the audience at the Republican Jewish Coalition’s Presidential Forum as he refused to declare Israel was the undivided capital of Israel. “Can I at least pin you down on Jerusalem as the undivided capital of Israel? Is that a position you support?” RJC Executive Director Matt Brooks asked.

“You know what I want to do? I want to wait until I meet with Bibi,” Trump replied. As he was loudly jeered by an audible member in the room, Trump turned to his left and asked, “Who’s the wise guy? Do me a favor, just relax. You’ll like me very much, believe me. Don’t worry about it.”

The Republican presidential hopeful also pledged to back Israel “very strongly” as president, in his interview with The Brody File on CBN News. “I just see what is happening and I am so saddened by this Iran deal. It’s one of the worst deals I’ve ever seen under any circumstances, any deal, not just deals between nations. I think it’s a tremendous liability to Israel,” said Trump. “I think it’s going to actually lead to nuclear proliferation and it’s going to cause a lot of problems.”

“I will be very good to Israel,” he pledged. “We have a president that I think is the worst thing that has ever happened to Israel. But I will be backing it very strongly. They’re our best ally. They’re our best ally in the Middle East. They’ve really been loyal to us. We have not been loyal to them.” Trump backed his pledge by noting that he has “so many friends from Israel,” that he has “won so many awards from Israel” and “was even the grand marshal for the Israeli Day Parade” in 2004.
