(CNN) A group of protesters bearing a message as stark as their red and white costumes are opposing Brett Kavanaugh's Supreme Court confirmation hearings.

The group's restrained method was a sharp contrast to other scenes going on throughout the Senate side of Capitol Hill. Police arrested 70 people by the end of the day for "unlawful demonstration activities."

Inside the hearing, protesters shouted out, and Democrats immediately demanded the hearing be stalled until thousands of documents from Kavanaugh's time as a Bush-era White House lawyer are reviewed.
