The Trump administration is considering an offer from Republican mega-donor Sheldon Adelson to pay for at least part of a new U.S. embassy in Jerusalem, four U.S. officials told The Associated Press.

Lawyers at the State Department are looking into the legality of accepting private donations to cover some or all of the embassy costs, the administration officials said. The discussions are occurring as the new embassy clears its final bureaucratic hurdles. On Thursday, Secretary of State Rex Tillerson ended weeks of delay by signing off on a security plan for moving the embassy from Tel Aviv to the holy city, according to the officials, who weren't authorized to discuss the issue publicly and demanded anonymity.
