President Donald Trump said Wednesday his attorney general should terminate "right now" the federal probe into the campaign that took him to the White House, a newly fervent attack on the investigation that could imperil his presidency.
White House press secretary Sarah Huckabee Sanders scrambled to explain that Trump's tweet was "not an order" and the president was not directing his attorney general to do anything.
"It's the president's opinion," she said.
But Trump's early morning tweetstorm again raised the specter that he could try to more directly bring special counsel Robert Mueller's Russia-Trump election-collusion probe to a premature end. And it revived the idea that the president's tweets themselves might be used as evidence that he is attempting to obstruct justice.
Meanwhile, Trump attorney Rudy Giuliani said negotiations are continuing to have Trump sit down for questions from Mueller, though the lawyer said, "I'm not going to give you a lot of hope that it's going to happen." He said both sides had exchanged proposals for conditions for such an interview, "and yesterday we got a letter back from them and now we're in the process of responding."
Trump has raged privately in recent days that both the forces of government and the media are trying to undermine him. That includes trumped-up charges against his former campaign chairman, Paul Manafort, and distorting the outcome of the Helsinki summit to make it appear he was beholden to Russia, according to two Republicans close to the White House who were not authorized to discuss private conversations and spoke on condition of anonymity.
Trump was closely monitoring news coverage of the Manafort proceedings, which provoked the spate of incendiary tweets, according to the two Republicans and two White House officials.
"The president's not obstructing, he's fighting back," said Sanders, dismissing the idea that Trump's tweets could be tantamount to obstruction of justice.
The most inflammatory of Trump's tweets said, "This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA!"
After complaining about the tough questions he received from American reporters in Finland, Trump has largely steered clear of the mainstream media, instead opting for safer spaces like an interview with ally Rush Limbaugh this week. From the White House briefing room podium on Wednesday, Sanders declined to denounce the harassment of a CNN reporter during a Trump rally in Florida on Tuesday.
The president's social media outburst renewed discussion of the significance of his tweets.
Giuliani stressed that Trump was just issuing an opinion, though he also said the White House believes "the investigation should be brought to a close."
"I guess, if we were playing poker we're not put up or shut up, what do you got?" Giuliani said. "We have every reason to believe they don't have anything."
When pressed by reporters on how she tells the difference between a presidential order or an opinion, Sanders said Trump makes his intentions "pretty clear."
But the line between registering an opinion or governing by tweet has bedeviled the White House from the start, even when former press secretary Sean Spicer declared tweets could be official White House statements. Earlier this year, Trump blindsided the Defense Department when he tweeted out a transgender ban for the military, prompting the Pentagon to slow walk the program.
Mueller already is interested in some of Trump's tweets to the extent they raise obstruction of justice concerns. Though experts believe obstruction by tweet is possible, prosecutors have to prove beyond a reasonable doubt that a particular act got in the way of an investigation and that the person who did it intended to obstruct.
The president's tweets on Wednesday were greeted warily on Capitol Hill, with most lawmakers, regardless of party, urging Trump to let the probe run its course.
No. 3 Senate GOP leader John Thune of South Dakota said, "The idea that they should truncate it doesn't make sense to me." Democratic Sen. Richard Blumenthal of Connecticut went much further, declaring: "There is now highly credible evidence that the president of the United States is committing obstruction of justice in real time, right before our eyes."
