Witnesses who are called to the offices of the special counsel are whisked in through the loading dock of an office building in Washington.
WASHINGTON – A white sedan whisked a man into the loading dock of a glass and concrete building in a drab office district in southwest Washington. Security guards quickly waved the vehicle inside, then pushed a button that closed the garage door and shielded the guest’s arrival from public view.
With his stealth morning arrival last week, White House Counsel Donald McGahn became the latest in a string of high-level witnesses to enter the secretive nerve center of special counsel Robert Mueller’s investigation into Russian interference in the 2016 election.
Twenty-hours later, Mueller and his team emerged into public view to rattle Washington with the dramatic announcement that former national security adviser Michael Flynn would plead guilty to lying to the FBI.
The ensnaring of Flynn, the second former aide to President Donald Trump to cooperate with the inquiry, serves as the latest indication that Mueller’s operation is rapidly pursuing an expansive mission, drilling deeper into Trump’s inner circle.
In the past two months, Mueller and his deputies have received private debriefs from two dozen current and former Trump advisers, each of whom has made the trek to the special counsel’s secure office suite.
Once inside, most witnesses are seated in a windowless conference room where two- and three-person teams of FBI agents and prosecutors rotate in and out, pressing them for answers.
Among the topics that have been of keen interest to investigators: how foreign government officials and their emissaries contacted Trump officials, as well as the actions and interplay of Flynn and Jared Kushner, the president’s son-in-law.
Often listening in is the special counsel himself, a sphinx-like presence who sits quietly along the wall for portions of key interviews.
This picture of Mueller’s operation – drawn from descriptions of witnesses, lawyers and others briefed on the interviews – provides a rare look inside the high-stakes investigation that could implicate Trump’s circle and determine the future of his presidency.
The locked-down nature of the probe has left both the witnesses and the public scrutinizing every move of the special counsel for meaning, without any certainty about the full scope of his investigation.
Trump and his lawyers express confidence that Mueller will swiftly conclude his examination of the White House, perhaps even by the year’s end. Trump’s Democratic opponents hope the investigation will uncover more crimes and ultimately force the president’s removal from office.
Meanwhile, some witnesses who have been interviewed came away with the impression that the probe is still unfolding.
“When they were questioning me, it seemed like they were still trying to get a feel of the basic landscape of the place,” said one witness who was questioned in late October for several hours and, like others, requested anonymity to describe the confidential sessions. “I didn’t get the sense they had anything incriminating on the president. Nor were they anywhere close to done.”
White House lawyer Ty Cobb said he believes the probe’s focus on Trump’s White House is wrapping up, noting that all White House staffer interviews will be completed by the end of next week.
“At the end of the interviews, it would be reasonable to expect that it would not take long to bring this to conclusion,” Cobb said. “I commend the Office of Special Counsel for their acknowledged hard work on behalf of the country, to undertake this serious responsibility, and to perform it in an expedited but deliberate, thorough way.”
At least two dozen people who traveled in Trump’s orbit in 2016 and 2017 – on the campaign trail, in his transition operation and then in the White House – have been questioned in the past 10 weeks, according to people familiar with the interviews.
The most high profile is Kushner, who met with Mueller’s team in November, as well as former chief of staff Reince Priebus and former press secretary Sean Spicer. Trump policy adviser Stephen Miller and former foreign policy adviser J. D. Gordon have also been interviewed.
White House communications director Hope Hicks was scheduled to sit down with Muller’s team a few days before Thanksgiving. Mueller’s team has also indicated plans to interview senior associate White House counsel James Burnham.
McGahn, who was interviewed by Mueller’s prosecutors for a full day Thursday, was scheduled to return Friday to complete his interview. However, the special counsel postponed the session as a courtesy to allow McGahn to help the White House manage the response to Flynn’s plea, a person familiar with the interview said.
Cobb declined to say which White House aides remain to be interviewed.
Several people who worked shoulder to shoulder with Flynn have also been interviewed by Mueller’s operation. That includes retired Gen. Keith Kellogg, the chief of staff to the National Security Council, as well as several people who worked with Flynn Intel Group, a now-shuttered private consulting firm.
Mueller’s group has also inquired whether Flynn recommended specific foreign meetings to senior aides, including Kushner. Investigators were particularly interested in how certain foreign officials got on Kushner’s calendar and the discussions that Flynn and Kushner had about those encounters, according to people familiar with the questions.
During the transition, Kushner and Flynn met with the Russian ambassador to the United States, Sergey Kislyak. At the early December meeting, Kushner suggested establishing a secure communications line between Trump officials and the Kremlin at a Russian diplomatic facility, according to U. S. officials who reviewed intelligence reports describing Kislyak’s account.
Kushner has said that Kislyak sought the secure line as a way for Russian generals to communicate to the incoming administration about U. S. policy on Syria.
Trump’s son-in-law has also been identified by people familiar with his role as the “very senior member” of the transition team who directed Flynn in December to reach out to Kislyak and lobby him about a U. N. resolution on Israeli settlements, according to new court filings.
The volume of questions about Kushner in their interviews surprised some witnesses.
“I remember specifically being asked about Jared a number of times,” said one witness.
Another witness said agents and prosecutors repeatedly asked him about Trump’s decision-making during the May weekend he decided to fire FBI Director James Comey. Prosecutors inquired whether Kushner had pushed the president to jettison Comey, according to two people familiar with the interview.
Kushner attorney Abbe Lowell declined to comment on what the president’s son-in-law discussed at his November session with Mueller. “Mr. Kushner has voluntarily cooperated with all relevant inquiries and will continue to do so,” he said.
Two administration officials said that it would be natural for investigators to ask a lot of questions about Kushner, whom Trump put in charge of communicating with foreign officials, adding that such inquiries do not indicate he is a target.
The special counsel has continued to make ongoing requests for records from associates of the Trump campaign, according to two people familiar with the requests. The campaign associates aren’t expected to finish producing these documents by the end of the year. Mueller’s team is also newly scrutinizing an Alexandria, Virginia-based office that ran foreign policy ideas for the campaign.
