Sen. Richard Blumenthal, D-Conn., took aim at Secretary of Defense Lloyd Austin after the military leader's Senate testimony on Afghanistan, saying Austin had provided "no real responses."

"There really was no clarity. And with all due respect to the Secretary of Defense, he provided no real responses to my questions because at the moment, there aren’t responses. There is nobody in charge," he said during an appearance on MSNBC Tuesday.

Blumenthal also argued that the U.S. has a "moral imperative" to get "tens of thousands of Afghan allies, the former interpreters, translators, guards, security officials who went into combat with our troops" out of the country.
