But Guttenberg says that when he introduced himself as the father of a Parkland victim and tried to shake Kavanaugh's hand during a break in the hearings, the nominee turned and ignored him.
"Just walked up to Judge Kavanaugh as morning session ended. Put out my hand to introduce myself as Jaime Guttenberg's dad. He pulled his hand back, turned his back to me and walked away," Guttenberg tweeted around 1:30 p.m. "I guess he did not want to deal with the reality of gun violence."
An AP photographer was there to document the moment. The striking image, which some observers are already calling a defining moment in Kavanaugh's hearings, backs up Guttenberg's narrative:
CSPAN's cameras captured the moment as well:

White House officials later suggested that security personnel "intervened" before Kavanaugh had a chance to decide whether to shake Guttenberg's hand, but the video seems to show several seconds before the guards step between the men.

Kavanaugh's hearings haven't been going smoothly in general. Democrats have assailed Republicans for dumping 42,000 pages of documents from Kavanaugh's time in the George W. Bush White House at the last minute and slammed Trump for refusing to disclose another 100,000 pages of documents related to Kavanaugh's career.
Protesters also repeatedly interrupted the hearings, which Democratic Sen. Patrick Leahy called a "sham."
“This is the most incomplete, most partisan, least transparent vetting for any Supreme Court nominee I have ever seen,” he said.
In light of Guttenberg's encounter, it bears mentioning the NRA has promised to spend upward of $1 million on ads supporting Kavanaugh's Supreme Court bid.
