The Wall Street Journal reports that Special Counsel Robert Mueller has requested Cambridge Analytica, the data firm that worked for President Trump's campaign, turn over the emails of all employees who were involved with the campaign.

The Journal says it was a voluntary request, as was another from the House Intelligence Committee, which the company went along with. The paper also reports Cambridge Analytica CEO Alexander Nix was interviewed by the House Intelligence Committee via video call this week as part of its investigation into Russian meddling in the 2016 presidential election.

In October, The Daily Beast reported that Nix sent an email to a third party that said he contacted WikiLeaks founder Julian Assange about how he could assist his website with releasing some of Hillary Clinton's deleted emails. Assange told The Daily Beast he was able to "confirm an approach by Cambridge Analytica and can confirm that it was rejected by WikiLeaks." Catherine Garcia

White House attorney Ty Cobb says that on Tuesday, Special Counsel Robert Mueller announced he's finished the interviews he requested with about two dozen current and former White House witnesses as part of the investigation into Russian meddling in the presidential election.

Attorneys have refused to say which White House officials have been interviewed, but it's been reported that White House communications director Hope Hicks, White House counsel Don McGahn, former Chief of Staff Reince Priebus, and former Press Secretary Sean Spicer have all spoken with investigators. Mueller could still ask for additional interviews with the staffers and others who have not yet been questioned.

Cobb had said he thought the interviews would be finished by Thanksgiving and Mueller would announce the investigation was complete by the end of the year, but one attorney representing a senior Trump administration official in the probe told Politico that's a "nonsensical" timeline. "You say what you need to say to keep the sun coming up in the morning, but if you woke Ty Cobb up in the middle of the night and ask him if he thinks this is really going to be over in three weeks I think his answer is, 'Are you f—ing kidding me? Of course it won't.'" Catherine Garcia

Special Counsel Robert Mueller's team has requested that the Department of Justice hand over documents related to President Trump's firing of former FBI Director James Comey and Attorney General Jeff Sessions' decision to recuse himself from the investigation of the Trump's campaign and any connections to Russian officials, a person familiar with the matter told ABC News on Sunday.

The special counsel is reportedly looking into whether Trump attempted to obstruct the federal investigation, and the request for documents, delivered within the past month, is the first such request from Mueller's team to the Justice Department. Specifically, ABC News reports, Mueller has asked for communications between DOJ officials and their counterparts at the White House. Catherine Garcia

In mid-October, Special Counsel Robert Mueller's team caught more than a dozen of President Trump's top campaign officials by surprise when he issued a subpoena requesting documents related to Russia, a person with knowledge of the situation told The Wall Street Journal on Thursday.

The officials had been sharing with the special counsel the same documents they were giving congressional committees investigating Russian meddling into last year's election, the person said. The subpoena, the first official order for information from Trump's campaign, did not compel any of the recipients to testify before Mueller's grand jury, the Journal reports. "Sending a subpoena to an entity that says it has been cooperating with document requests isn't unusual in cases in which prosecutors have some concern that their demands aren't being met promptly or aren't being entirely fulfilled," the Journal explains. "A subpoena can serve as a backup, to make sure the recipient is complying as promised, and as a reminder that failure to provide documents as demanded would count as obstructing a grand-jury investigation."

Former House Speaker Newt Gingrich slammed the Russia probe staff brought on by Special Counsel Robert Mueller as being "bad people" on Good Morning America on Tuesday, despite less than a month ago praising Mueller's credentials.

Mueller earned widespread bipartisan support when he was appointed in May to head the independent investigation into the Trump team's possible ties to Russian election meddling. Weeks later, though, President Trump's allies have soured on Mueller despite his "unblemished" reputation and service under presidents of both parties, in the words of The New York Times.

Some are even calling for President Trump to fire Mueller, although Gingrich wouldn't go that far. But "Mueller's first four hires were all Democrats," Gingrich stressed, adding: "These are bad people who are going to be after Trump." Watch below. Jeva Lange
