Republican lawmakers on the House Intelligence Committee jumped in ahead of opening statements from Wednesday's impeachment witnesses to call for a subpoena to compel testimony from the whistleblower who triggered the inquiry.

Schiff said the committee would have to vote to subpoena the whistleblower, and that such a vote would wait until after witness testimony.

Democrats, who hold the majority on the committee, seem certain to kill a motion to subpoena the whistleblower, who first raised concerns about Trump's July 25 call with the Ukrainian president.

Since the whistleblower's complaint, most if not all of the allegations have been overtaken by testimony from witnesses, who have testified about their concerns that Trump was pressuring Ukraine to conduct politically motivated investigations of 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.

Democrats have argued there is no reason to bring in the whistleblower given the subsequent testimony, and the whistleblower's attorneys have argued their client's anonymity should be respected.

Schiff responded that he would only do so if it members were seeking to publicize the identity of the whistleblower.

"We will do everything necessary to protect the whistleblower's identity, and I'm disturbed to hear members of the committee ... seek to undermine those protections by outing the whistleblower," Schiff said.

Trump and his Republican allies have made the anonymous whistleblower a central part of their efforts to undermine allegations of wrongdoing by the president. Trump and Republicans have called for the whistleblower to testify, despite the additional testimony and documents corroborating the bulk of the individual's original claims.

GOP members of the Intelligence Committee on Wednesday displayed a poster that alleged Schiff has known the identity of the whistleblower for more than 90 days.

But Schiff has said those claims are false and that he does not know the person's identity.
