I forget which liberal dumba$$ kept saying Roberts will make all the evidentiary decisions, but here again is another source saying not only will the Senate GOP make the decision as to what comes in, they can override any decision Roberts makes on the fly.
If they don't allow hearsay evidence like Lispey is saying the democrats wouldn't be able to put on a single witness they've called so far lol.
