President Trump followed up on Sunday evening his previous night's tweetstorm on the investigations into his campaign's alleged ties to Russia with more tweets and retweets on the matter. And he lashed out at former President Obama in some posts — days after his predecessor criticized him.

The big picture: Trump addressed Obama's comments that were leaked to Yahoo News calling his response to the novel coronavirus pandemic a "chaotic disaster" and warning the "rule of law is at risk" over the Justice Department dropping of charges against former national security adviser Michael Flynn.

  • Trump is facing pressure from many conservative allies to fire FBI director Christopher Wray due to the bureau's handling of its investigation of Flynn.
  • His tweetstorm on the FBI and the House Intelligence Committee probes show how consumed he is by what he believes to be an illegal attempt to end his presidency by Democrats and intelligence officials from the Obama administration.

The other side: Democrats on the House Judiciary Committee on Friday accused Attorney General Bill Barr of doing Trump's "political bidding" by interfering in ongoing criminal cases, and called on the DOJ's inspector general to investigate.

Driving the news: Michelle Obama said Monday night that from coronavirus deaths to the economy to foreign alliances and racial justice, Trump has sewn "chaos, division and a total and utter lack of empathy."

On opening night of their awkward but stirring virtual convention, Democrats prioritized racial justice along with the pandemic and the recession.

Why it matters: On issues, Joe Biden's widest margin over President Trump in a new NBC News/Wall Street Journal poll is race relations — a 24 point spread.
