Hillary Clinton’s former campaign spokesperson is leading a campaign to get Supreme Court Justice Brett Kavanaugh fired from a summer teaching job at George Mason University, according to a report.

Demand Justice, a liberal advocacy group run by Clinton’s 2016 campaign press secretary Brian Fallon, is running a Facebook ad campaign targeting students at George Mason University, Fox News reports. Fallon’s ads ask students to sign a Change.org petition to oust Kavanaugh from his summer teaching gig at the university due to sexual assault allegations against him.

“His confirmation to the Supreme Court does not absolve him of guilt, and he should not be given a platform to teach,” said Fallon. “We stand with survivors and urge the George Mason University administration to fire Kavanaugh.”
