“His campaign was sending out recorded calls to activists in Iowa telling them Ben Carson has dropped out, inform everyone at the caucus site,” Rubio told CBS News’ Major Garrett Wednesday. “It was a concerted effort that I’m sure they planned to execute on something in order to influence the election.”…

“I think that’s evidence of a campaign and of a candidate that’s willing to do — in this case — or say anything to win,” Rubio said in his interview. “And I think that’s real problematic.”

He added: “I think that we’ll be revisiting this issue in South Carolina.”

Rubio further defended Carson as a candidate who “deserves more respect than what Ted and his campaign gave him.”
