Washington (CNN)Republican Sen. Lindsey Graham on Sunday advised President Donald Trump against pulling troops out of Afghanistan, warning of "disastrous" consequences if the US dipped below keeping at least 8,600 troops in the country.
"Mr. President, if you don't have a counter-terrorism force left behind, even if you've got to deal with the Taliban -- which I doubt, but you might -- they don't have the capability or will to protect the American homeland," the South Carolina senator said on CBS' "Face the Nation."
"In one day, we lost 3,000 Americans because we took our eye off the ball in Afghanistan," Graham said. The senator has in the past urged Trump to maintain an American military presence in the country.
Trump has repeatedly advocated for bringing US troops back from Afghanistan, putting him at odds with hawkish Republican lawmakers like Graham.
Graham said he is "concerned" that Trump is going to "make the same mistake that President Obama did in Iraq" by pulling out the troops.
"You may get a peace deal with the Taliban, but you'll never get a peace deal with al Qaeda or ISIS," Graham said.
The senator said he was going to introduce legislation requiring the US Secretary of Defense and the US Secretary of State to "certify to the Congress that to go below 8,600 does not create an additional national security risk to the homeland."
