Washington (CNN) Twitter began suspending 70 pro-Mike Bloomberg accounts on Friday for breaking its rules, a Twitter spokesperson confirmed to CNN.

The accounts were posting identical messages in support of Bloomberg and ran afoul of Twitter's rules against "platform manipulation and spam," a Twitter spokesperson said.

Bloomberg campaign spokeswoman Sabrina Singh told CNN on Sunday that staff had not been deceitful.

"We ask that all of our deputy field organizers identify themselves as working on behalf of the Mike Bloomberg 2020 campaign on their social media accounts," she said in a statement. "Through Outvote, content is shared by staffers and volunteers to their network of friends and family and was not intended to mislead anyone."

The Los Angeles Times first reported the suspensions on Friday.
