In an interview with Fox News host Sean Hannity, Kupec said John Durham — the U.S. attorney for Connecticut whom Barr tasked last year with probing the origins of the investigation into Russian interference in the 2016 election and potential coordination between the Russian government and the Trump campaign — “had been looking at the issue of unmasking” as part of his review.

“The attorney general determined that certain aspects of unmasking needed to be reviewed separately as a support to John Durham’s investigation,” Kupec said, “so he tapped John Bash, one of our U.S. attorneys out of Texas, to do just that.”

LOL….This is in regard to a small part of unmasking probe, which was separated from the main probe. That's why Barr tapped Bash. If we learned anything we learned Bash is a cuck.
