I'm editing this sentence:
Keep in mind that the judge, and probably a law clerk too, [have/has] read your ?>papers and submissions and [are/is] familiar with the case."
The question is whether the 'have' and 'are' should be singular referring to the judge, or plural because there's reference to the clerk as well. To me, it reads better in the singular since the clerk is added as an aside. Which is correct in this situation?
