Hope Hicks, one of Donald Trump’s longest-serving and most loyal aides who decamped to head up Fox’s communications department, will cooperate with a Democratic investigation into her former boss. According to CNN, the former presidential “security blanket” is planning to turn over documents and notes about Trump, his campaign, and his time in office to the House Judiciary Committee, which has launched a wide-ranging probe into the president. Hicks’s cooperation could cause major headaches for the president, who has bemoaned that Democrats have “gone stone cold CRAZY” in investigating him.

“They won’t get ANYTHING done for our Country!” he tweeted earlier this month.

Jerrold Nadler, chairman of the House Judiciary Committee, announced the probe on March 4, seeking documents from 81 individuals and organizations in an effort to sniff out potential obstruction of justice, public corruption, and abuse of power by Trump. “This is a critical time for our nation, and we have a responsibility to investigate these matters and hold hearings for the public to have all the facts,” Nadler said in a statement at the time. “That is exactly what we intend to do.” This hasn’t sat well with Trump, who has fired off several belligerent tweets in the days since, and whose allies have sought to stonewall Democrats’ requests.

So far, Nadler has reportedly received documents from eight of the 81 parties, not including Hicks. That might look good for Trump, until you see who has complied: Tom Barrack, who led the Trump Inaugural Committee, turned over 3,349 pages; Steve Bannon, Trump’s former chief strategist, turned in 2,688; and the National Rifle Association, which has been scrutinized for its ties to Russia, turned in 1,466. The Trump Inaugural Committee and campaign advisers J.D. Gordon, George Papadopoulos, and Sam Nunberg also handed in documents, as did Rinat Akhmetshin, the former Russian intelligence officer present for Donald Trump Jr.’s infamous Trump Tower meeting in 2016. Ike Kaveladze, an associate of the Trump-linked Agalarov family who was also at the meeting with Trump Jr., Jared Kushner, and Paul Manafort, has likewise cooperated with investigators, his lawyer told CNN.

It’s unclear what information Hicks could provide the panel, but the 30-year-old was seen as one of Trump’s closest, most loyal aides in the White House. She’d worked for him at the Trump Organization since 2014, served as press secretary for his long-shot campaign, and rose to communications director during his time in the White House, where she played the role of gatekeeper for the unconventional president. Hicks mostly maintained a low profile in the White House, but drew scrutiny at times, including in 2018 when The New York Times reported that she helped Trump craft the misleading statement his son initially used to explain away the Trump Tower meeting. Information from Hicks on that episode could be significant for Nadler’s probe into obstruction of justice. “I found that she had a deep knowledge of what was going on in the organization, the campaign, the transition, and the administration,” Rep. Eric Swalwell said of Hicks on MSNBC Thursday morning. “She’s going to have to tell us who she lied for.”

Of course, how much she shares remains to be seen. Before resigning her post last year, she testified in a closed-door hearing before the House Intelligence Committee that she had told “white lies” on Trump’s behalf. But she insisted she did not lie about anything relevant to the investigations into Russia's interference in the 2016 presidential election and declined to answer all of the questions from Democrats, then the minority, about her time on the transition or in the White House. Ultimately, it’s unclear how much information she’ll provide this time around. Either way, the involvement of someone who witnessed the innermost workings of his presidency is likely to serve another blow to Trump’s ailing psyche—particularly if that testimony is public, which Swalwell intimated is a possibility. “She is, just like Michael Cohen, a witness who has seen a lot,” he said, adding that a televised testimony “would be of high value considering how much she knows.”
