Hey, everyone. I'm David Chalien, the CNN political director. This is the Daily D.C. impeachment watch.

Last week, we saw the ceremonial start of the Senate impeachment trial of President Donald Trump.

Today, the proceedings kicked off in earnest. Take a listen to Majority Leader Mitch McConnell

on the Senate floor today, outlining what the next steps of the Senate trial will be

if indeed his rules resolution is adopted. After pre-trial business, the resolution establishes

the four things that need to happen next.

First, the Senate will hear an opening presentation from the House managers.

Second, we will hear from the President's Council.

Third, senators will be able to seek further information by posing written questions to either

side through the Chief Justice.

And fourth, with all that information in hand, the Senate will consider whether we feel

any additional evidence or witnesses are necessary to evaluate

whether the House case has cleared or failed to clear the high bar of overcoming the presumption

of innocence and undoing a democratic election.

And now take a listen to Minority Leader Chuck Schumer express outrage over that very

proposed McConnell resolution.

On something as important as impeachment, the McConnell resolution is nothing short of a national

disgrace. This will go down, this resolution, as one of the

darker moments in the Senate history, perhaps one of even the darkest. Now, Leader McConnell has just

said he wants to go by the Clinton rules. Then why did he change them in four important ways at minimum

to all make the trial less transparent, less clear, and with less evidence?

Needless to say, there's a lot of partisan rancor at the outset of the trial.
