On January 18, the U.S. Court of Appeals, D.C. circuit, heard oral argument in Stein v Federal Election Commission, 21-1213. The three judges are Karen Henderson (a Bush Sr. appointee), Robert Wilkins (an Obama appointee), and Gregory Katsas (a Trump appointee). The issue is whether Jill Stein, Green Party presidential nominee in 2016 must repay $175,000 in primary season matching funds. Stein has two arguments, a constitutional argument and a statutory interpretation argument, and either one by itself would relieve her of the need for any repayment.
The hearing seems to have gone reasonably well, and the oral argument link will be available later. Check back if that is interesting to you.
