"We will not confirm or deny any name that is published or promoted by supporters of the President," the whistleblower's attorneys, from the Compass Rose Legal Group, said in a statement earlier this month. "Disclosure of any name undermines the integrity of the whistleblower system and will deter any future whistleblowers."

Trump has also previously called for the media to reveal the whistleblower's identity.

The Hill has not named the individual, and it is typically the policy of major news outlets not to reveal the identity of whistleblowers, who are federally protected against retribution.

The whistleblower's complaint raised concerns about the phone call between Trump and Zelensky in which the two leaders discussed former Vice President Joe Biden Joe BidenFormer Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick Bloomberg rolls out M ad buy to boost Biden in Florida MORE and his son Hunter Biden. The complaint also alleged "efforts to restrict access to records related to the call."

The White House has now released a rough transcript of the July 25 call, and the House has launched an impeachment inquiry into Trump. The whistleblower's attorneys argue that their identity has become irrelevant due to the release of information that supersedes the complaint.

Trump again said Friday the impeachment inquiry is part of an ongoing "witch hunt" against him and connected it to former special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE's investigation into Russian attempts to help Trump in the 2016 election.

"We went through the whole Russia hoax ... I had about three days of rest and then I had this thing hit me based on a perfect phone call with a very nice person who I think is going to do a good job," Trump told Bongino, who is a Fox News contributor. "This is just out of the blue that this came up."
