For JS 34 [1] Mitch McConnell (R, KY) limited debate to 10 minutes--I'm unclear from the transcript exactly how this was allowed. Richard Blumenthal (D, CT) offered resistance to limiting debate, and Kamala Harris (D, CA) and Patrick Leahy (D, VT) requested the role be called several times as a delaying tactic, but the limiting of debate went through.
Just prior to the vote, Brian Schatz (D, HI) offered some debate, but this is cosmetic given the known votes.
My read there is little to be gained by trying to legislate implementation power that has been ceded to the executive branch and the various agencies that are run by appointment, and therefore a costly filibuster and fight was not worth the time, effort and political mud.
