I had totally forgotten that John Bash is the husband of Zina Bash.
https://en.wikipedia.org/wiki/Zina_Bash :
"… earlier, she clerked for Brett Kavanaugh of the United States Court of Appeals for the District of Columbia Circuit … In July 2018, she was named senior counsel on the executive leadership team of Texas Attorney General Ken Paxton, but had left by August to assist Judge Kavanaugh during his Supreme Court nomination hearing before the Senate."

"On May 27, 2020, a Justice Department spokeswoman said that Attorney General William Barr had assigned Bash to review practices of the Trump-Russia investigation related to the 2016 "unmasking" of Trump's advisor Gen. Michael Flynn in a phone call with Russian Ambassador Sergey Kislyak."
