Here’s a heads up on something. There are a number of questions about what kind of articles of impeachment will be voted against President Trump and what wrongdoing they will cover. But it’s generally assumed that we know the relevant facts those articles will be based on. Don’t be so sure.

The actual articles, the report that goes with it and the evidence presented at a Senate trial will likely contain at least one pretty substantial surprise – and not a good one for President Trump.

In what’s seen as an attempt to poke holes in House Democrats’ impeachment case, White House officials are disputing the details of Trump lawyer Rudy Giuliani’s contacts with White House aides during key moments in the Ukraine pressure scheme. Here’s more on that and other stories we’re following.

I’ve seldom considered a public question in which the two possible answers both seem quite so compelling and convincing as this one. Late last month I said I had grave misgivings about ending the Impeachment inquiry, as the House appears intent on doing, without having deposed any of the key players in the scandal. The list is long: Rudy Giuliani, Mick Mulvaney, Mike Pompeo, John Bolton in addition to as many as a dozen others. Stopping here seems crazy on several fronts: There are numerous key questions that remain unanswered. There are dimensions of wrongdoing that remain all but unexplored – side rackets pursued by Rudy Giuliani, his hustler pals Igor Fruman and Lev Parnas and others. These unknowns appear to contain at least substantial venal corruption, likely subversion of US foreign policy and even possible subversion by foreign nation states.

For all of these reasons, ones that are both substantive and narrowly political, it seems crazy to leave these questions unanswered. And yet I think they should. People talk about whether the Democrats should go small or go big. I think it’s more whether they should go fast or go slow. (After all, it’s easy enough to add on an obstruction article based on the Mueller Report. The work is already done.) I think they’re right to go fast, even as I agree that the arguments to the contrary are powerful and compelling.

Here are my four reasons.

Happy Thursday, December 5. President Donald Trump took a stab at explaining away his damning request for a favor from Ukraine President Volodymyr Zelensky on the July 25 call. Here’s more on that and the other stories we’re watching.

Did Sheldon make a big purchase? From TPM Reader AM …

I’d written you previously about Pompeo’s likely senate run. Just reading that piece in McClatchy now about the warchest he’s amassing and the outreach he’s doing to megadonors and this caught my eye:

Some aspects of Wednesday’s impeachment hearing — the first in front of the House Judiciary Committee, the panel with jurisdiction for advancing the ultimate articles of impeachment — felt like déjà vu all over again.

Rudy Giuliani picked a precarious moment to arrive in the Ukrainian capital: days before crucial talks are to begin with Russia over a potential deal to end the war in the country’s east.
