UPDATE: Mueller report summary delivered to Congress
The special counsel did not find Trump campaign or associates conspired with Russia.
"The special counsel's investigation did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. Presidential Election," Attorney General William Barr wrote in a letter to Congress.
The Justice Department on Sunday submitted to Congress a summary of the main conclusions from special counsel Robert Mueller's investigation.
Democrats have demanded that Barr make Mueller's full report public and provide the special counsel's underlying evidence to Congress. They are threatening to subpoena and take the Trump administration to court if they're not satisfied with what the Justice Department provides.
"We will try to negotiate. We will try everything else first. But if we have to, yes, we will certainly issue subpoenas to get that information," House Judiciary Chairman Jerry Nadler said on CNN's "State of the Union" Sunday.
A White House spokesman said Sunday the White House had not received or been briefed on the Muller report.
But Trump's allies have pointed to the fact that no additional indictments are coming from the Mueller probe as vindication for the President.
The special counsel's investigation ended Friday after Mueller submitted his confidential report to Barr for review.
The 22-month special counsel probe led to charges against 37 defendants, which included six Trump associates, 26 Russians and three Russian companies. Seven defendants have pleaded guilty, and one, Trump's former campaign chairman Paul Manafort, was convicted at trial.
While Mueller's investigation is over, several criminal investigations are still ongoing.
They relate to an alleged Russian conspiracy to blast political propaganda across Americans' social media networks; Manafort's political colleague from Russia, Konstantin Kilimnik; and what Manafort's deputy and a central Trump political player, Rick Gates, knows, according to court records.
Another is a grand jury's pursuit of documents from a company owned by a foreign government. That subpoena for documents began with Mueller last year.
The DC US Attorney's Office will pick up many of the open court cases, including Gates and former Trump adviser Roger Stone. And the US Attorney's Office in Manhattan continues to look into Trump's inauguration and allegations waged by Trump's former attorney and fixer Michael Cohen.
