Attorney General Barr might release the Mueller report's 'principle conclusions' this weekend

Special Counsel Robert Mueller has finished his report, but hardly anyone knows what's in it.

The Department of Justice announced Friday afternoon that Mueller had finished his investigation into potential ties between President Trump's campaign and Russian election interference. Attorney General William Barr similarly told the House and Senate Judiciary committees he had received the report Friday — and said he might tell them what's in it "as soon as this weekend."

In a letter to the committees on Friday, Barr said that Mueller faced "no such instances" where he was blocked from taking an action he wanted to pursue. There had been concerns that President Trump would not submit to in-person questioning by Mueller, but if this was something Mueller attempted, it was seemingly not blocked.

"Only a few people" have seen the report so far, a Department of Justice official told CNN's Shimon Prokupecz after its conclusion. Barr has refused to commit to releasing the whole report to the public or even to Congress, but he said in his Friday letter that he may have Mueller's "principle conclusions" ready for the judiciary committee "as soon as this weekend." Barr continued to say that he would "consult with" Mueller and Deputy Attorney General Rod Rosenstein "to determine what other information can be released to Congress and the public," and added that he "remain[s] committed to as much transparency as possible."
