hmm, so far no senators have addressed the chamber. So I suppose that impeach managers are first, to argue admissiblity of "new evidence" from the (D) list. Whether this list is a copy of Schumer's 11 Amd. list I could not say. Perhaps someone "leaked" a (D) list to press?

Is an (R) list circulating in private or public?

The roster is not not alternating. So far House managers have the floor and are still abusing video clips* to demonstrate indisputable and disputed testimony. Which is problematic in defense of House witnesses corroborate each other's hearsay testimony and Art. II, obstruction a/k/a "cover-up". Jeffries nominates Mulvaney, Duffy, and Blair (OMB)--but his contribution may be incomplete. Jeffries (third spkr?) is followed by Gomez--who just resurrected Bolton's "forthcoming book" in lieu of redacted docs--followed by HUAC Rev. Chairman Mr Manager Schiff's concealment-fair trial monologue.

* House evidence admitted to the senate for consideration: yesterday Crapo et al. solicited an accounting by R/WH managers.

PHILBIN....There were 17 witnesses who were deposed and testified--12 in public, 17 who were in closed hearings below. So far you have seen in these presentations 192 video clips from 13 different witnesses. ... I think the more official number is 28,578 pages. So you have got over 28,000 pages of documents submitted into the record provisionally in evidence in this trial, subject later to potential objections for hearsay and other evidentiary objections.

Johnson et al. resurrected the credibility of witnesses Misko, Vindman, and the whistle-blower-he-cannot-be-named.

RECESS!

HUAC Rev. Chairman Mr Manager Schiff returns with a proposal: one (1) week to depose witnesses called by "both sides"; (2) senate agreement to depute the C.J. in disputes on the admissibility of witnesses, according to existing senate rules; (3) senate agreement on deposition time limits; and a long digression into the obligations and responsibilities of the senate to TRY and DELIBERATE probative evidence of the POTUS impeachable conduct, to follow the NORMS of trial by jury ...

C.J. recognizes majority leader. Quorum call begins.
alrighty then.
