Trey Gowdy, a South Carolina congressman who supports Marco Rubio, called for Ted Cruz to repudiate the most recent bit of "underhanded tactics" ahead of the South Carolina primary.

"In the last week, we have seen a systematic effort by Sen. Cruz and his allies to spread false information and outright lies in the hopes of winning votes by appealing to our lowest common denominator," Gowdy said. "Now, Its been reported that a fake Facebook page has been used to fool South Carolinians into thinking that I no longer support Marco Rubio and that I'm instead supporting Ted Cruz.

"Nothing could be further from the truth and I'm demanding that Sen. Cruz and his campaign repudiate these dishonest and underhanded tactics," Gowdy continued. "We can have a debate about the future of our party and our country. But we need not leave our integrity behind."

In the Facebook post at hand by a page titled "Trey Gowdy Prayers," it says that the most recent debate "revealed [Rubio's] total lack of integrity, intillect and foresight," before switching the faux endorsement to Cruz.

"It is official, I have changed my mind. My previous endorsement of Marco Rubio was a grave mistake. The recent South Carolina debate revealed his total lack of integrity, intillect and foresight," the post reads. "To all my Christian and Conservative friends in South Carolina, I hereby formally endorse Ted Cruz for President of the United States."

The disavowed page makes no mention of it being a fake page. The page description reads, "A Page to post Prayers and receive updates on Trey Gowdy, Chairman of the Congressional Select Committee on Benghazi."

The page comes on the heels of a string of questions thrown at the Cruz campaign about whether they promoted rumors that Ben Carson was dropping out of the race on Iowa caucus night.

The Cruz campaign did not respond to the Washington Examiner's request for comment by press time.

UPDATE (3:24 p.m.): Responding to Gowdy's comments, Cruz spokesman Rick Tyler criticized the Rubio surrogate for "throwing around wild accusations without any evidence whatsoever," pointing specifically to the Facebook page, which he said the Cruz campaign had nothing to do with

"This is called a smear campaign, and it's beneath the dignity of a sitting member of the House of Representatives," Tyler said before asking, "does the Marco Rubio campaign really believe it's going to smear it's way to victory?"
