The answer to the question asked of Blinken as to who specifically is holding Mark Frerichs in Afghanistan, is apparently classified.
"Republican Pennsylvania Rep. Scott Perry pressed Blinken about “documents to the FBI related to Hunter Biden, Burisma or the Blue State Strategies Corporation” during a House Foreign Affairs Committee about President Joe Biden’s withdrawal from Afghanistan. Blinken responded by saying he does not know what Perry is referring to. He would not deny being interviewed by the FBI, saying it would be inappropriate to comment.
“My concerns continue to escalate with regard to Secretary Blinken’s credibility and judgment. I was informed that the Secretary was interviewed by the FBI with regard to Hunter Biden, Burisma, and his Blue Star Strategies. The Secretary’s response, and evident discomfort thereof, was very telling,” Perry first told the Daily Caller after the questioning.
The Daily Caller contacted the State Department to which they did not immediately respond."

Malinowski pointed out that a withdrawal under President Trump wouldn't have any Afghans being brought to the United States. He made the comment as if that would be a bad thing.
Blinken said that they make no differentiation between those born in the United States, and those who have been naturalized.
