Michigan Senate Republicans have blocked Democratic Gov. Gretchen Whitmer's appointee to a commission that regulates hunting and fishing. Democrats say Thursday's mostly party-line vote rejecting Anna Mitterling of Mason to the Natural Resources Commission was done because the GOP opposes a different nominee to the commission who supports gun control. It marks the first time in nearly a decade that a governor's nominee was rejected by the Senate. Whitmer named Mitterling, a Lansing Community College adjunct biology professor, to the commission in December.
