Suffice it to say, he wasn't thrilled.
Trump's wish may come true.
He went on to call for Feinstein to face a "tough" primary challenge in her 2018 reelection campaign. But Billionaire activist Tom Steyer, long rumored to be pondering a bid, will not get in the race - according to the L.A. Times.
Trump lashed out at Feinstein, the senior Democrat on the Senate Judiciary Committee, Wednesday morning, after she unilaterally released a transcript of testimony from the founder of the firm behind the infamous Trump dossier.
In a tweet, Trump referred to the the top Democrat on the Senate Judiciary Committee as "sneaky" and stated her release of the more than 300-pages of interviews between Glenn Simpson and Judiciary Committee lawmakers and attorneys was "possibly illegal".
Fusion GPS, which was hired first by Republicans and later Democrats, studied various aspects of Trump's background, a typical function for opposition researchers during presidential campaigns. In an op-ed in the New York Times a little more than a week ago, Glenn Simpson and Peter Fritsch, the co-founders of Fusion GPS, alleged they were being targeted to divert attention from the main issue. Grassley told reporters Wednesday that he had not been involved in any leaks.
A revelation that the Russian Federation collusion investigation was sparked by the dossier, a piece of opposition research paid for by the Clinton campaign and the DNC, would prove to be a massive scandal.
The investigation led by special prosecutor Robert S. Mueller III has so far led to a guilty plea from Trump former national security adviser Michael Flynn and charges against former Trump campaign chairman Paul Manafort.
A Grassley spokesperson, in a statement, called Feinstein's release of the transcript "confounding" and said her action "undermines the integrity of the committee's oversight work and jeopardizes its ability to secure candid voluntary testimony relating to the independent recollections of future witnesses".
