* Heidi Przybyla reports that Democrats aren't wasting any time trying to get more information on the Mueller report:

House Judiciary Committee Chairman Jerrold Nadler has contacted the Department of Justice to set a date for Attorney General William Barr to testify on special counsel Robert Mueller’s Russia report, according to a senior aide involved in the process. Those discussions are taking place as some committee Democrats are saying Barr must fill in more blanks on the report within the next week, according to a lawmaker and senior leadership aide.

Committee Democrats are huddling this evening to discuss their next steps, according to two lawmakers on the committee.

I wouldn’t be surprised if Barr tries to slow-walk the release of the report, letting it drag on for months until everyone has moved on. That shouldn’t be allowed to happen.

* John Wagner and Felicia Sonmez report on how the Trump administration is trying to use the Barr letter to drive us all insane:

The Trump campaign on Monday sent an email to TV producers warning about guests who have made “outlandish, false claims” about the president’s Russia connections, asking networks to use “basic journalistic standards” when making future bookings.

The memo, titled “Credibility of Certain Guests,” comes after Trump — who made 8,158 false claims during his first two years as president -- repeatedly made the false assertion that Mueller’s report exonerated him on obstruction of justice.

Trump campaign director of communications Tim Murtaugh included in the memo a list of Democratic lawmakers and others who have alleged that there was collusion between Trump’s campaign and the Russian government during the 2016 campaign.

Never forget that there is real political power in shamelessness.
