In the run-up to President Donald Trump's decision last month to recognize Jerusalem as Israel's capital, Vice President Mike Pence, a conservative Christian who had long advocated for the move, did something he does only selectively: speak up.

As intelligence and diplomatic officials warned against the change, Pence made a forceful "closing argument" in favor of it at a White House Situation Room meeting, leading a group that included senior adviser Jared Kushner and U.S. Ambassador to the United Nations Nikki Haley, a senior administration official said.

Pence helped persuade Trump to fulfill a campaign promise and upend long-standing U.S. policy by declaring he recognized Jerusalem as the capital of Israel, over objections from Arab nations and many Western allies.
