Washington CNN  — 

The House Intelligence Committee and lawyers for the whistleblower who filed a complaint about President Donald Trump’s conduct are discussing extreme measures to protect the individual’s identity amid growing concerns about his or her safety, according to several sources familiar with the process.

The news comes after Trump has said he wants to know the whistleblower’s identity and sought to discredit the anonymous individual as a partisan actor who misconstrued the details of his call with the Ukrainian leader. This despite the fact that a rough transcript of the conversation released by the White House only seemed to corroborate many of the details in the complaint filed with the Intelligence Community Inspector General.

It is still unclear when the whistleblower might ultimately talk with the committee. But talks are underway looking at several options to attempt to prevent the whistleblower from being identified or having his or her name leaked to the press.

Among the measures being discussed are the possibility of using an off-site location, limiting Hill staff and members who would be present and even disguising the individual’s image and voice, the sources said. Any secure facility, known as a SCIF, could be used for the meeting, potentially the facilities located at Langley or Ft. Meade.

There are also ways to bring the whistleblower up to Capitol Hill without being seen by the press, including what one source described as the “Petraeus treatment,” referring to the former CIA Director and commander of US Central Command, David Petraeus’ private testimony from years back.

An aide to one Democratic member on the House Intelligence committee told CNN that discussions about masking the whistleblower’s voice and face have been prompted by concerns that Republicans could leak the individuals identity to the Trump administration or the press.

“The President and several high profile Republican Members have made it clear they don’t think the whistleblower deserves protection,” the aide said. “Once the whistleblower’s identity is known, they will do everything they can to attack this person’s credibility.”

Sources familiar with the situation have told CNN that the whistleblower’s lawyers are still working on obtaining the appropriate security clearances so they can accompany their client to the meeting with lawmakers and/or Hill staff and that process appears to be ongoing.

Last week, the attorneys representing the whistleblower released two new letters from the Office of the Director of National Intelligence, stating the whistleblower protections would also apply to any disclosures the individual made to congressional intelligence committees.

CNN reported last month that the whistleblower’s legal counsel “wrote to the Acting Director of National Intelligence to request specific guidance as to the appropriate security practices to permit a meeting, if needed, with the Members of the Intelligence Oversight Committees.”

The meeting could take place on the condition that acting Director of National Intelligence Joseph Maguire approves appropriate security clearances for the individual’s legal counsel so that they can accompany their client, correspondence obtained by CNN showed.

Protecting the whistleblower’s identity remains a major priority for legal counsel who has raised concerns about their client’s personal safety amid attacks from President Donald Trump and some of his Republican allies who have sought to discredit the complaint detailing concerns about Trump’s communications with the president of Ukraine.

While the whistleblower’s lawyers have declined to comment on specific security practices that may be implemented, they have noted that they have the client’s safety in mind at all times. As of last week, the client was still going to work and continuing to go about their normal daily tasks, according to two sources familiar.

A source familiar with efforts to protect the whistleblower’s personal safety told CNN that a group of retired Navy SEALs have come forward to offer assistance. While the extent of that assistance remains unclear, the source suggested that the SEALs could be used to provide personal security at places like the whistleblower’s home.

Concerns about the whistleblower’s safety escalated last week amid rumors that a media outlet was preparing to publish the individual’s name, prompting the attorneys to send out a flurry of tweets urging the media to refrain from outing their client.

While the whistleblower’s name was ultimately not published, the possibility that their client could be outed at anytime remains a major concern for the attorneys.

Irvin McCullough, a national security analyst at the Government Accountability Project, said the whistleblower should feel some level of comfort following comments made by Maguire at a public hearing recently that supported the whistleblower but added that it’s “a hard road ahead to protect their anonymity when members and the President indicate they’d like to question the whistleblower directly.”
