Democratic Senators Mazie Hirono, Kamala Harris, Richard Blumenthal, and Sheldon Whitehouse just explained why they walked out.

Sen. Mazie Hirono said it's "because it’s very clear that the Republicans will break every norm, every rule, to get this person on the Supreme Court." She said Brett Kavanaugh would arrive with "a cloud" and would "weaken the court" as a result. "This has got to stop. So I walked out. I’m not going to participate in this charade anymore," she said.

Sen. Kamala Harris said, "From top to bottom this has been about bullies. Listen to the people. All we have asked for is that there be an FBI investigation."

She said Kavanaugh accuser Christine Blasey Ford "poured out her heart and "gave the process dignity and respect."

"The least we could do is give her the dignity and respect of a process that has credibility," she said. "We are talking about putting on the United States Supreme Court for a lifetime."

"For the sake of our democracy and the integrity of our democracy you would think that members of the United States Senate would say wait a minute, there’s enough here to push pause," she said. "Let’s reflect on what we’re about to do."

Sen. Richard Blumenthal added, "All of America is watching the United State’s Senate today... and they should be deeply embarrassed ... there are two who should be called as witnesses ... there needs to be an FBI investigation ..”
