A top Republican is joining Democrats’ calls for the public release of former Special Counsel Robert Mueller’s source material.

Rep. Devin Nunes (R-Calif.), ranking member of the House Intelligence Committee, made his demand in a Friday tweet, saying the documents will prove that Mueller’s investigation was a “fraud.”

“This is why we need all backup and source documentation for the #muellerdossier [to be] released publicly,” he posted. “It’s all a fraud.”

The tweet came in reaction to a Twitter investigator who noted that the Mueller Report’s damning summary of a phone call that was part of his probe of former National Security Adviser Michael Flynn removed exonerating passages that the complete transcript of the call, which was released Friday under court order, included.

Intelligence Committee Democrats have also called for the release of Mueller’s evidence – not to attack the special counsel’s work, but to pursue a possible impeachment investigation into President Trump.
