Senate Majority Leader Mitch McConnell made a rare break with President Donald Trump and proposed a measure urging the U.S. to continue the fight against Islamic State and al-Qaida in Syria and Afghanistan and avoid any "precipitous withdrawal."

McConnell said an amendment he plans to offer to legislation that would impose new sanctions on Syria and that it would reassure U.S. allies in both countries.

"It would recognize the danger of a precipitous withdrawal from either conflict, and highlight the need for diplomatic engagement and political solutions to the underlying conflicts in Syria and Afghanistan,' he said on the Senate floor. "We have seen the costs of a precipitous withdrawal before in Iraq. And in Afghanistan, we have seen the downsides of telling the enemy they can just wait us out."
