Appearing on “State of the Union” with CNN’s Dana Bash, Klain said the U.S. government has been in close contact with the Americans still left in the country who have been located.

“We believe it’s around a hundred,” he said. “We’re in touch with all of them, who we’ve identified, on a regular basis. Obviously, we’re hopeful that in the coming days that the Qataris will resume air service out of Kabul. And if they do, we’re obviously going to look to see if Americans can be on those flights.

“We are going to find ways to get them, the ones that one to leave, to get them out of Afghanistan,” he added. “We know many of them have family members, many of them want to stay, but the ones that want to leave, we’re going to get them out.”
