The House Select Committee investigating the Jan. 6, 2021, Capitol riot subpoenaed Wisconsin House Speaker Robin Voss over the weekend, demanding he testify Monday morning, prompting Voss to file an emergency lawsuit.   

  Voss asked a federal judge in Wisconsin to block the subpoena, which called for him to testify at 10 a.m.  ET on Monday, two days before the commission’s next public hearing, according to federal court records.  However, Voss is not appearing before the committee on Monday after his attorney spoke with the committee and the House received copies of his court filing, according to a person familiar with Voss’ subpoena.   

  The judge has not yet responded.   

  CNN has reached out to the committee for comment.   

  Voss says the committee wants to question him about a conversation he had with former President Donald Trump last July after state courts blocked the use of some absentee ballots and Trump “asked President Voss to take future action” .   

  “The Commission is asking Chairman Vos to appear on the stand to answer questions unrelated to the Commission’s investigation, almost without warning, in the final days of his re-election campaign, simply because of the Commission’s public relations scheme,” the suit states. of.   

  Vos challenges the House committee’s authority in court and argues that the subpoena “seeks to violate Chairman Vos’ legislative immunity” from lawsuits.   

  Similar lawsuits by other House witnesses have not been successful or have yet to be decided.
