The case is the second involving Mosby that will be argued before the 4th Circuit. Also pending is an appeal by Keri Borzilleri, a former assistant state's attorney who argued she was wrongly fired because she supported Mosby's opponent in the 2014 election. A federal judge dismissed the lawsuit, saying prosecutors are "at-will" employees and can be fired for having a different viewpoint. Borzilleri now works as a special assistant U.S. attorney.
