Good evening to you this Sunday. I'm Ari Melburgh, and welcome back to our MSNBC special impeachment

White House in Crisis. We're joining you tonight with a new special report, the first in this series

since this week's historic House vote on those new rules for impeaching President Donald Trump.

All of this coming after a series of bombshells and testimony by Trump's own administration officials.

The Congress now on record with the exact plans for how any Trump impeachment will proceed.

Investigators preparing for these public hearings.

And an expert panel joins me at the top of our show to walk through everything that has just changed.

Later tonight, we also have exclusive reporting

on how Congress approaches the impeachment and trial of a president. Lessons Democrats are eyeing,

plus potential new cracks in Donald Trump's firewall. Also later tonight, a guest debuting on this

series for the first time with new reporting on the people who could make or break

Donald Trump's presidency now, his lawyers.

All of that in our special, starting now.

Those in favor, please say aye.

Aye.

We take no joy in having to move down this road.

This is the moment that history will write.

It's a real big scam.

Just like the impeachment of your president is a scam.

What is its stake is our democracy?

Well, that's not even supposed to declare.

The House and the American public must see all the evidence for themselves.
