A pro-Marco Rubio super-PAC has launched attack ads against Trump, funded by a new cash injection of more than $10 million. And late on Friday afternoon, The Hill learned that another anti-Trump super-PAC — Our Principles PAC, which is run by Katie Packer, a former senior adviser to Mitt Romney, who was the party’s 2012 nominee — would be putting into national rotation an attack ad hitting the billionaire for hiring illegal immigrants.

“There’s a lot of people recognizing that Donald Trump is a fraud and there’s lots of interest in shining a spotlight on it,” Packer told The Hill in a telephone interview on Friday.

“I think different groups have different issues that they’re interested in highlighting,” she added. “There’s plenty of fodder. It’s a very target-rich environment.”

The barrage against appears to be in sync with the attacks that Marco Rubio levied against Trump in Thursday night’s CNN debate. Rubio escalated these attacks in his public appearances on Friday, describing Trump as a “con artist.”
