The Washington Post reports:
An important outside voice advising Trump to make the leap was Adelson’s, according to several people familiar with the two men’s conversations. At a White House dinner earlier this year, Adelson made the issue a main topic, one person said. In the months that followed, Adelson periodically asked others close to Trump what was causing the delay and expressed frustration, these people said.
At the same time, other Trump advisers were making their case against the move. Most prominent among them were Tillerson and Defense Secretary Jim Mattis. Tillerson, mindful of the death of four Americans in militant attacks in Benghazi, Libya, in 2012, “pushed back vocally,” one White House official said. Already at odds with Trump over other aspects of the president’s approach to the Middle East, Tillerson argued that the move could unleash a dangerous chain reaction across the region.
Several advisers said he did not seem to have a full understanding of the issue and instead appeared to be focused on “seeming pro-Israel,” in the words of one, and “making a deal,” in the words of another. Once Trump indicated 10 days ago that he would not sign a second waiver, national security adviser H.R. McMaster began putting together options that officials assessed would result in the least damage.
