▶ Watch Video: Austin says “we’re not close” yet on pace of evacuations from Afghanistan President Biden on Wednesday declined an opportunity to say he would have done anything in Afghanistan differently, insisting he doesn’t know how the U.S. could withdraw from Afghanistan without “chaos ensuing.” The president made the comments in an interview with ABC’s George Stephanopoulos, the first time he’s taken questions from a journalist since the Taliban took over Afghanistan. “So you don’t think this could have been handled — this exit could have been handled better in any way, no mistakes?” Stephanopoulos asked Biden in a clip of the interview posted Wednesday. “No, I don’t think it could have been handled in a way that, we’re gonna go back in hindsight and look — but the idea that somehow, there’s a way to have gotten out without chaos ensuing, I don’t know how that happens,” the president responded. “I don’t know how that happened.” Stephanopoulos asked if that was “always priced into the decision.” “Yes,” the president responded, adding, “Now exactly what happened, I’ve not priced in.” The president has defended his decision to withdraw from Afghanistan and the timing, even amid the spectacle of chaos at Kabul’s airport, where thousands of Americans and Afghans who helped the U.S. are stuck and desperately trying to leave. Mr. Biden told Stephanopoulos the Taliban is “cooperating, letting American citizens get out,” but added that the U.S. is having “some more difficulty having those who helped us when we were in there.” The U.S. embassy has told Americans it cannot guarantee their safe passage to the airport in Kabul, and Defense Secretary Lloyd Austin told reporters Wednesday the U.S. military does not have “the capability to go out and collect large numbers of people.” It’s not yet clear how long the thousands of troops sent to Afghanistan to ease the mass evacuation of the country will stay or even whether they’ll be in Kabul beyond August 31. So far, the U.S. military has taken more than 3,000 people out of the country, and relocated nearly 2,000 Afghan special immigrants, according to State Department spokesperson Ned Price. White House press secretary Jen Psaki said Tuesday there are roughly 11,000 self-identified Americans in the country. The U.S. is relying on assurances from the Taliban to allow the safe passage of Americans trying to reach the airport, since the U.S. has not been providing transportation to the airport. CBS News has learned the State Department is optimizing its outreach to American citizens in Afghanistan and others, based on the experience of the past several days. Democratic lawmakers are vowing to investigate what went wrong with U.S. intelligence and decision-making that led to the scenes unfolding on television. Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, said earlier this week he will work with other committees to ask “tough but necessary questions” about why the U.S. wasn’t better prepared. On Monday, the last time the president addressed Afghanistan publicly and the first time he addressed Afghanistan since Kabul fell to the Taliban, conceded the departure from Afghanistan has been “hard and messy,” but stood by his decision. National security adviser Jake Sullivan said Tuesday the president takes responsibility for every decision made regarding Afghanistan. “I stand squarely behind my decision. After 20 years, I’ve learned the hard way — that there was never a good time to withdraw U.S. forces,” Mr. Biden said Monday.
