I would use Janice Brown as the nuclear option if I had to make a recess appointment. If she is willing, her appointment would be valid for two years until the next Congress is seated in 2022. Just prior to 2022, can you see the Dems trying to force the first black woman off the court. At 70, Brown has no other way to get on the court so she may be willing to take a recess appointment that would cement her place in Judicial history.
Want to bet that almost no black youngsters have even heard of her? She is the kind of example they really need. She came up back when real racism was still common, and prevailed over it.
