President Donald Trump's national security adviser will be traveling to Israel and Turkey in early January to discuss what the White House says is the "deliberate and coordinated" withdrawal of U.S. forces from Syria.

National security adviser John Bolton also will be discussing increased cooperation with the Turkish military and other partners.

Bolton's spokesman, Garrett Marquis, said in a statement Monday that Bolton will be joined in Turkey with Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, and James Jeffrey, the secretary of state's special representative for Syria engagement.

On Sunday, Republican Sen. Lindsey Graham of South Carolina said Trump had initiated a "pause" on his surprise decision to withdraw all roughly 2,000 American troops in Syria. Trump has faced bipartisan criticism since announcing the drawdown two weeks ago.
