The Rubio campaign is accusing rival candidate Ted Cruz of spreading a culture of deceit in his own campaign.

Cruz on Monday asked for the resignation of his spokesman, Rick Tyler, for spreading a story that falsely alleged that Rubio insulted the Bible. Rubio asked whether Cruz intended to fire anyone over the incident.

Cruz then announced that he had asked for Tyler’s resignation. Rubio’s campaign dug in.

Rubio spokesman Alex Conant says Tyler is "a really good spokesman who had the unenviable task of working for a candidate willing to do or say anything to get elected."

He adds that "It’s high time for Ted Cruz to do the right thing and stop the lies."

The incident comes after the Cruz campaign falsely cast a news story as evidence that Ben Carson was quitting the GOP nomination fight.

Rubio and Cruz are vying for the support of core GOP voters to challenge front runner Donald Trump
