Robert Mueller submits Russia report

House Intelligence Committee Chairman Rep. Adam Schiff said on Friday that his panel was willing to subpoena special counsel Robert Mueller, if needed, in order to obtain a clearer picture of the contents of his final report.

"If necessary, we will call Bob Mueller or others before our committee," he told CNN's Wolf Blitzer, predicting that the Judiciary Committee may summon Attorney General Bill Barr for testimony as well.

Barr received Mueller's completed report Friday, and could brief House committee leaders on its key conclusion as soon as this weekend.

Schiff continued:

"This began as a counterintelligence investigation by the FBI. It began as the same in our committee, and we have a right to be informed and we will demand to be informed about it," he added.

Schiff did not say whether the Mueller's potential testimony would occur behind closed doors or publicly.

Hear the moment:

As President Trump and White House officials digest the news that special counsel Robert Mueller's investigation has concluded, Republican donors are milling about Mar-a-Lago.

The Palm Beach GOP dinner is being held at Mar-a-Lago tonight. Attendees have been hanging around by the pool for a pre-reception and watching as White House officials come and go, one source at Mar-a-Lago said.

So far: There is no sighting of the President.

Special counsel spokesman Peter Carr confirmed there are 10 remaining prosecutors under special counsel Robert Mueller.

Six are on detail from the Justice Department and four joined the office directly from private practice. 

Carr at this time is referring all other questions to the Department of Justice.

These are the prosecutors who are on detail:

There’s a larger number of staffers with President Trump in Palm Beach this weekend than normal, sources tell CNN. 

Not only is he joined by several members of his legal team, including heavy weights Pat Cipollone and Emmet Flood, but also other members of the legal team, both press secretaries and several other officials.

What usually happens: Typically, when the President travels to his Mar-a-Lago resort, only a handful of staffers join him. 

The halls of the West Wing were quiet today as officials waited for the Justice Department to announce that special counsel Robert Mueller's investigation was over.

Several say they were surprised that Attorney General William Barr said he could provide information about the report “as soon as this weekend,” but feel it signals good news for the White House.

Judiciary Committee spokesman Daniel Schwarz told CNN that a Department of Justice official stopped by to the House Judiciary office right around 5 p.m. ET, where the majority and minority counsel representatives received the one-page letter in a manila envelope.

It was a short meeting.

The majority counsel provided a copy to Chairman Jerry Nadler -- he is in New York, so they read it over the phone with him.

There are no further meetings on the Hill planned in person tonight.

Every prosecutor seen entering the office this morning was gone by 4 p.m. ET.

Scott Meisler walked out with a backpack and suitcase, stopping briefly to take a photo of the flock of cameras outside. Rush Atkinson, Michael Dreeben, James Quarles, Andrew Goldstein, Elizabeth Prelogar, Aaron Zebley and Adam Jed had all either driven or walked out of the building. Aaron Zelinsky, the last man standing, left at 3:38 p.m. ET.

Where was Robert Mueller? One minute later, the head of the special counsel's security sped out of the garage and drove north in Robert Mueller's car. No one else was in the car.

The press outside the garage was buzzing for the first time all day. About 10 minutes later a woman in a compact car drove out saying, "He's coming, he's coming." Then, the silver Ford expedition drove out of the building.

Was Mueller inside? All clues point to yes because this car was likely used this morning, at about 7:11 a.m., to bring in Mueller.

This morning a silver Ford Expedition with tinted windows — a vehicle that CNN's stakeout team has previously seen used to transport witnesses and persons of interest — entered the garage. Curtis Heide, an FBI agent known on the team, was driving. Was Mueller in the backseat? It was impossible to tell.

GOP Sen. Chuck Grassley called for Attorney General William Barr to provide Robert Mueller's findings to Congress and the public "to finally put an end to the speculation and innuendo that has loomed over this administration since its earliest days." 

"Attempts to keep the collusion narrative alive, especially for political reasons, will only serve to further harm our political discourse and play into the hands of our foreign adversaries," he said in a statement.

Read his full statement:

Rep. Jerry Nadler tweeted a copy of the letter Attorney General William Barr sent House and Senate Judiciary leaders notifying them that Robert Mueller had concluded his investigation.

Trump campaign press secretary Kayleigh McEnany referred CNN to White House press secretary Sarah Sanders' statement "at the moment."

CNN has previously reported that the campaign was prepared to respond to the substance of special counsel Robert Mueller's report when it emerged publicly.
