Republican lawmakers this week openly mocked Sen. Cory Booker, D-N.J., for claiming to have an “I am Spartacus” moment when he claimed to violate Senate rules by releasing emails related to Supreme Court nominee Brett Kavanaugh, even though the emails had already been approved for release.

Booker insisted Thursday he was a Senate rule violator, even though the email he discussed in the hearing was OK’d for public release the night before. And after Booker dramatically laid claim to an “I am Spartacus” moment, Republicans mocked him for it.
