When President-elect Donald J. Trump’s Middle East envoy, Steve Witkoff, met with Prime Minister Benjamin Netanyahu of Israel on Saturday to pressure him on a cease-fire deal in Gaza, there was someone on the speakerphone: Brett H. McGurk, President Biden’s longtime Mideast negotiator.
It was a vivid example of cooperation between two men representing bitter political rivals whose relationship has been best described as poisonous. Rarely if ever have teams of current and new presidents of different parties worked together at such a high-stakes moment, with the fate of American lives and the future of a devastating war hanging in the balance.
Both Mr. Trump and Mr. Biden publicly claimed credit for the breakthrough.
“This EPIC ceasefire agreement could have only happened as a result of our Historic Victory in November,” Mr. Trump wrote on his social media site even before the deal was formally announced in the Middle East.
At the White House, Mr. Biden told reporters that his administration had worked tirelessly for months to convince the two sides to halt the fighting. He called it “one of the toughest negotiations I’ve ever experienced” and gave credit to “an extraordinary team of American diplomats who have worked nonstop for months to get this done.”
As he left the room, a reporter asked Mr. Biden, “Who gets credit for this, Mr. President, you or Trump?” Mr. Biden stopped, turned around and smiled.
“Is that a joke?” he asked.
But despite the tension between the current president and the next one, their representatives in the Middle East described a cooperative working relationship in the weeks since Election Day.
