The resolution, which condemned Israeli settlement building as illegal, was passed as the U.S. abstained despite calls from Trump and Israeli Prime Minister Benjamin Netanyahu for the Obama administration to veto the measure.

Trump even intervened to pressure Egypt, the resolution’s sponsor, to delay the vote.

The president-elect’s vow to negotiate a peace agreement comes a week after announcing his pick for ambassador to Israel, David Friedman, a hardliner who has challenged a two-state solution to the conflict.
