Also, if [they] want Bolton to testify? Fine. Let's call him up. And then let's call up everyone else that vindicates POTUS, INCLUDING the Bidens, Hussein, Lynch, HRC, etc My only problem with your statement above is that to start calling witnesses now go against the exact point that Starr made.    It's the Houses job to conduct the investigative side of an Impeachment.  They should spend what ever time it takes to exhaust the witnesses, to get to the truth. His important point -  To now rely on the Senate, to do what the house did not do, will forever change the rules, the framework, the rules on impeachments going forward.  This is not just a matter of more witnesses, it goes to the hear of the rules that have governed the impeachment process for 150 years.    One rule I learned sailing on the ocean, "Never take unnecessary risk". And old sailor told me once that I should wear deck shoes.  I ask why? He said, you might stub your toe, and die. I ask, how would a stubbed toe kill me? He explained it sort of along chaos theory where a major malfunction, death, results from a series of cascading failures.  If you would not have stubbed your toe, it would not have gotten infected.  If your toes was not infected, you would not have gotten sick with fever. If you were not sick with fever, you would have gotten on deck fast enough to take in your sails before the gale hit, if you would have taken in your sails in time, you would not have broached in the gale, if you would not have broached, you would not have gone over board and drowned. Indeed my death was caused by a stubbed toe. I think the same rule applies to everything.  They should not allow witnesses, get out before they stub their toe.
