President Trump lashed out at Sen. Dianne Feinstein on twitter for unilaterally releasing the full transcript an interview between congressional investigators and the founder of Fusion GPS, the opposition research firm that commissioned the controversial dossier on Trump during the 2016 campaign.

In a tweet, Trump called the top Democrat on the Senate Judiciary Committee “sneaky” and said her release of the more than 300-pages of interviews between Glenn Simpson and Judiciary Committee lawmakers and lawyers was "possibly illegal."

Trump also called for Feinstein to face a primary challenge in her reelection campaign in 2018.

"The fact that Sneaky Dianne Feinstein, who has on numerous occasions stated that collusion between Trump/Russia has not been found, would release testimony in such an underhanded and possibly illegal way, totally without authorization, is a disgrace" adding "Must have tough Primary!"

Trump will probably be disappointed. As The Hill explains, a tough primary is unlikely as California’s primary system rewards the top two finishers, irrespective of party, and Feinstein’s only notable challenger at this point is a Democrat.

That said, the California Democrat's release of the Simpson interviews caught Republicans by surprise and provided explosive new details that both parties will look to use to their advantage in the myriad investigations taking place on Capitol Hill surrounding the Trump campaign, Russia, the FBI the Department of Justice.

As reported last night, the dossier has been central to those investigations, with Democrats claiming it to be a roadmap to alleged collusion and corruption by Trump while Republicans and the Trump inner circle insisting that it is full of unverified claims that the FBI might have used to improperly secure a warrant to spy on Trump’s campaign and transition.

And speaking of Russian collusion, Trump also tweeted his anger "the single greatest witch hunt in American history” and demanded that Republicans “take control” of the Russia investigations."
