Rep. Jim Jordan (R- Ohio) has accused Intelligence Committee Chairman Adam Schiff (D-Calif.) of violating the House rules and the impeachment resolution set up by the Democrats after they voted down Republican subpoena request.

The House committee, which led the impeachment inquiry against President Donald Trump, on Wednesday, Nov. 20, rejected a Republican bid to issue subpoenas for an anonymous whistleblower and former Vice President Joe Biden’s son Hunter, Reuters reported.

The committee voted to set aside the motion to compel testimony by the whistleblower and Hunter Biden.

Earlier on Wednesday, Republican Reps. Devin Nunes (R-Calif.) and Jim Jordan (R-Ohio) sent a formal request to Schiff.

In the request letter, they argued that their request has been “repeatedly rejected” though Schiff asserted in September that the whistleblower would provide “unfiltered testimony” “very soon,” and though House Speaker Nancy Pelosi (D-Calif.) promised that the whistleblower would “speak directly to the House and Senate Intelligence Committees as required by law.”

The Republicans lawmakers claimed that Schiff reversed course to deny the whistleblower an opportunity to testify despite revelations that the whistleblower has a bias against President Trump.

The letter argues that “the whistleblower’s testimony is necessary for a full and fair understanding of all relevant facts.”

Nunes and Jordan also claimed that Schiff had repeatedly refused to allow Republicans to fully examine the role of Hunter Biden on the director board of Burisma Holdings, a corrupt Ukrainian company, during Vice President Biden’s term in office.

“Because witnesses explained that Hunter Biden’s presence on Burisma’s board raised concerns during the Obama administration and President Trump briefly raised this issue during his phone call with President Zelenskiy, this information is directly relevant to the Democrats’ ‘impeachment inquiry’,” the two Republicans argued.

The Republican congressmen also wanted to subpoena three other businesses for records relevant to Democrats’ impeachment inquiry, including Rosemont Seneca Bohai LLC, Hunter’s company.

They claimed that Schiff and the Democrats’ failure to concur with the subpoenas would constitute evidence of “denial of fundamental fairness and due process.”

However, Democrats opted to vote in a party-line to kill the Republican request.

In a response, Jordan, ranking member of the House Oversight and Reform Committee, blamed Schiff for his violation of both the House rules and their own impeachment resolution.

“First @RepAdamSchiff denies Republican witnesses. Now he violates House rules AND the Dems’ rigged impeachment resolution. All to deny Republican subpoenas for witnesses and documents,” Jordan wrote, citing a clause in the resolution to support his point.

“This is a sham on top of a sham,” he wrote.
