An aide for Judiciary Committee Chairman Chuck Grassley (R-IA) reportedly deleted a series of tweets this week after he was caught suggesting he was “unfazed” by sexual assault allegations against Supreme Court nominee Brett Kavanaugh.

Chief Counsel for Nominations Mike Davis, who works for Grassley, reportedly posted the remarks on Wednesday night. The tweets were captured by Adam Jentleson, a former staffer for Sen. Harry Reid (D-NV).

Davis also said that he is “determined to confirm” Kavanaugh to the Supreme Court.

According to Jentleson, Davis could be one of staffers to question Dr. Christine Blasey Ford about allegations that she was sexually assaulted by Kavanaugh.

Late last night Grassley’s chief counsel, who’d question Ford in a staff interview & prep Grassley’s questioning in a hearing, tweeted that he’s “unfazed” & “determined” to “confirm Kavanaugh,” then confirmed he personally conducted Kavanguah’s questioning & attacked Ford’s camp. pic.twitter.com/7ipvLqYxQP

By Thursday morning, Davis had deleted tweets.

Mike’s account has been locked. It was public this morning when these screen shots were taken. I’m leaving them up because the question of whether Grassley’s staff can conduct a fair investigation is central to the debate & Mike would conduct the questioning of Kavanaugh & Ford.

In a follow-up tweet, Davis insisted that his remarks were referring to “Democrats’ partisan political attacks” and not Ford’s allegations.
