Senate Minority Leader Mitch McConnell (R-KY) argued in a lawsuit on Friday that despite his “fierce opposition” to House Speaker Nancy Pelosi (D-CA) allowing proxy voting in 2020, he believes the courts should not interfere with Congress’s voting practices.

McConnell made the argument in an amicus brief drafted by former Attorney General Bill Barr and other lawyers, warning that a Texas federal court’s decision to declare some legislation that passed with proxy votes unenforceable was out of line. The case is now before the U.S. Court of Appeals for the Fifth Circuit.
