BREAKING: Biden White House rejects characterization of Americans stuck in Afghanistan as ‘hostage situation’

"So let me be very clear. We're in touch with American citizens. We're working to get them out. There are four who were able to depart overland," Psaki said.

"Our Secretary of State is in Qatar right now working on a range of options, including getting flights up and operational and going. And what we have seen is that individuals who have documentation are able to depart or that is what we have seen. But again, we don't have a great deal of understanding of every individual on these manifests," concluded Psaki.

Psaki's comments were made during the gaggle aboard on Air Force One on Tuesday, while the president was in route to New Jersey to survey damage from Hurricane Ida.

When asked about the ongoing humanitarian crisis, Psaki said that "we're doing a couple of things. One, the President signed an OFAC license just a few weeks ago, to ensure that humanitarian assistance from trusted groups like the World Food programs, and others can get on the ground."

An OFAC license is an authorization from the US Treasury that would give the "authorization from OFAC to engage in a transaction that otherwise would be prohibited."

Meanwhile, Secretary of State Antony Blinken held a press conference from Qatar on Tuesday and said the State Department is doing "accountings on the back end" of Afghan evacuees in the United States.

"In our effort to get as many people out as fast as we can while we had the airport functioning, we focused on doing just that," Blinken said, noting that State Department officials are "doing accountings on the back end as people arrive in the United States."
