Chances of witnesses being called later - the odds are against it. Chuck U tried six times today to force Republicans to agree.
They wouldnt bite.
this “hard” 5 minute break is now 18
I agree and here's a hypothetical situation to illustrate one reason why not.
When the proper time comes, by the rules, to request witnesses suppose the Dems ask for Bolton. Then Bolton has to be deposed privately. Every Senator will hear or read the deposition. Then they vote whether to allow Bolton as a witness.
Suppose Bolton's deposition is poison to the Dems. A party line vote could vote 'yes' to allow him to testify. The Dems couldn't complain, they requested him.
I don't think the Dems would take the chance. Once they request a witness there's no going back if McConnell and the Republicans agree to that process.
