President Trump’s defense opened Saturday with a swift 2-hour session that crammed everything but the kitchen sink into an argument that was designed first and foremost to undermine Adam Schiff’s reliability as a narrator. In a stinging irony, the White House lawyers maintained a sustained attack on the House managers for, of all things, hiding evidence.

I made sure to be in the Senate chamber right as President Trump’s legal team began to see how their tactics shifted the dynamics in the room.

It was the end of four long days of impeachment proceedings, and for once, all the senators were still.

For the bulk of House Intelligence Committee Chairman Adam Schiff’s speech closing the House’s presentation of evidence, every seat was filled (except for that of Sen. Jerry Moran (R-KS), who was watching from a public balcony with a guest).

News is out this morning that there’s a tape recording of President Trump ordering the firing of Marie Yovanovitch. On its face this doesn’t tell us dramatically more than we already know. The April 2018 dinner in question, where Lev Parnas and his business partner Igor Fruman met the President, has been reported on extensively. Even the gist of the conversation has been reported.

Obviously the existence of a tape adds some punch and drama. But that’s not the real significance.

House impeachment managers will spend their third day in the spotlight arguing that President Trump obstructed Congress by stonewalling congressional investigators’ requests for documents and witness testimony while the House was conducting its impeachment inquiry.

At the end of the day, the baton will be tossed to Trump’s legal team, who will begin their opening arguments on Saturday. The ever ratings-obsessed Trump is reportedly not happy that his lawyers’ first stab at his defense is taking place over the weekend, rather than during the week. Here’s more on that and other stories we’re following:

House impeachment managers dedicated a great deal of time today to explaining the current and historic political climate in Ukraine. Its prompted questions: Is this an effective strategy for Democrats? Or are we getting too far into the weeds?

There’s been much attention to what the senators have been doing during the long days of the impeachment proceedings: How are they reacting? Are they paying attention? Are they staying in their seats? Are they sleeping? What are they drinking?
