NEW: Some Senate Dems privately mull Biden-for-Bolton trade in impeachment trial, w/ interest in calling the GOP's bluff on "witness reciprocity" percolating behind closed doors.

And then the GOP will pull rug out from under them, refusing to permit Bolton to testify. In the meantime, they would get their win of a Dem “admission” that Biden is relevant, as bad as Dems claim Trump is, and did something really corrupt.

Ukraine op 2.0 accomplished. https://t.co/giyEPcuZBl
