- And now to the impeachment inquiry,

where chaos erupted during another day

of closed-door testimony on Capitol Hill.

Today's scheduled headliner,the Pentagon official

overseeing Ukraine, Laura Cooper.

Abigail Robertson joinsus now from the Hill

with what happened.

Abby?

- Well that's right, Jenna.

Almost two dozen House Republicans

marched into theclosed-door testimony today

demanding transparency on theongoing impeachment inquiry.

- We demand open proceedings.

The American people deserve nothing less.

- [Abigail] This interruption led

House intelligence chairman Adam Schiff

to postpone Laura Cooper's deposition,

which was already underwaywhen Democrats say

Republicans "crashed the party."

- We're gonna go in there today and demand

we get our rights as Members of Congress.

- [Abigail] GOP memberslambasted House Democrats

for making up the rules as they go.

- This is a Soviet styleimpeachment process.

This is closed doors.

It is unfair in every way.

- [Abigail] They alsostill demand Democrats

hold an official House impeachment vote

to authorize the inquiry.

- He wants us to believe thathe's like a special council

in these closed-door meetings over here.

- [Abigail] Congressman Lee Zeldin

who sits on one of theinvestigating committees

says nothing going on behindclosed doors is classified.

- This is the Democrats' strategy.

They like to cherry-pick leaks.

- [Abigail] Democratsargue this is the way

things are normally done.

- Investigations are not public.

When the investigation is done,there'll be public hearings.

That's how it's always been done.

- [Abigail] After Tuesday's hearing

with acting Ukraineambassador, Bill Taylor,

Democrats say histestimony proves there was

an implicit quid-pro-quobetween President Trump

and Ukrainian officials.

- This is my most disturbingday in Congress so far.

Very troubling.

- Democrats are also arguingthat over 100 House members

across various committeesare permitted to be

in the standing room only hearing room,

and they believe Republicansare trying to be disruptive

because they don't want to hear the truth.
