Amid a pitched partisan battle over how the Senate handles an allegation that Supreme Court nominee Brett Kavanaugh sexually assaulted a woman decades ago as a teenager, liberal groups on Thursday seized on comments from a Judiciary Committee staffer to paint the process as a sham.

Mike Davis, the committee’s chief staffer for nominations, tweeted twice overnight about his key role in the committee’s review of Christine Blasey Ford’s allegation, as well as criticism of Ford’s attorneys and his desired outcome of the process.

“Unfazed and determined. We will confirm Judge Kavanaugh. #ConfirmKavanaugh #SCOTUS,” Davis tweeted at 11 p.m. Wednesday.

Davis tweeted two hours later: “I personally questioned Judge Kavanaugh under penalty of felony and 5 years of imprisonment, if he lies. I’m still waiting to hear back from the accuser’s attorneys, who can’t find time between TV appearances to get back to me.”

The comments contrasted with the tone Committee Chairman Charles E. Grassley has tried to set in letters to committee Democrats as Ford’s attorneys have so far declined to have their client testify at a hearing the committee set for Monday, saying that she first wants an FBI investigation into her allegation.
