This is how Grassley should handle the hearing...
"It's been claimed that you tried to grope a girl when you were in HS and there were 2 or 4 witnesses. One of the witnesses has already denied that this happened. In addition we received a letter signed by 65 other women speaking very highly of your character in stark contrast to the claims of Professor Ford. We also know that your mother was the judge in a case where Professor Fords family lost. Our distinguished colleague, Senator Feinstein, sat on this information for weeks and weeks to delay your appointment to the Supreme Court. Judge Kavanaugh, are you guilty of this very vague accusation made by Prof Ford?"
"Nope"
"Thank you. This meeting is adjourned."
