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.
