How is the Democrats' impeachment inquiry going?

Well, it hit a bit of a snag on Tuesday night when Donald Trump's White House counsel,

Pat Sipolloni, released a letter saying that Trump would refuse any cooperation with

the House's impeachment inquiry.

It's an explanation with some legalese, and why the White House says they are in the

right to defy most of this probe, and they're also accusing the Democrats of using impeachment

oversight for 2020.

And the circumstances are that the impeachment inquiry has not been going very well for President

Trump over the past few days.

What really happened is that this kicked off with a former administration official, Kurt

Volcker, agreeing to testify and hand over documents last week.

That seems to have gone so bad for Trump that he's decided he's got to put a stop to this

whole thing.

And it was Volcker who handed over these texts, right?

Yeah.

So Kurt Volcker, he was the US Special Representative to Ukraine from 2017 up until

a little over a week ago when he resigned amidst this scandal.

And he went in to testify to congressional committees last Thursday.

But what really made the news from his testimony was a series of text messages that he handed

over to the committees.

And these text messages completely debunk Trump's line that there was no quid pro quo whatsoever
