Bernie Sanders rejects regret over early Graham Platner support despite ‘warning signs’

Sen. Bernie Sanders, I-Vt., rejected any regret Sunday on "Face the Nation" over his early support for former Maine Democratic Senate nominee Graham Platner, saying he urged Platner to withdraw once a former girlfriend accused him of sexual assault.

Host Margaret Brennan asked Sanders whether he regretted not acting sooner in response to earlier warning signs, saying that could have given Platner's replacement, former Maine Senate President Troy Jackson, more time to campaign.

"No, I don’t think so," Sanders said.
