In an appearance on ABC News’s “This Week,” Schiff (D-Calif.) echoed Pelosi’s message. He also said he expected the Intelligence Committee to hear from the whistleblower “very soon” pending a security clearance from acting director of national intelligence Joseph Maguire.

“We’ll get the unfiltered testimony of that whistleblower,” Schiff said, noting that Maguire said in a hearing Thursday that he would allow the whistleblower to testify privately without constraints.

One of the whistleblower’s attorneys, Mark Zaid, said in a statement that bipartisan negotiations in both chambers are ongoing “and we understand and agree that protecting the whistleblower’s identity is paramount.” He added that no date or time for the testimony has been set.

Andrew P. Bakaj, another lawyer representing the whistleblower, sent a letter Saturday to Maguire expressing fears for his client’s safety, citing remarks Trump made Wednesday calling the whistleblower “close to a spy” and alluding to the death penalty.
