Republican U.S. presidential candidate Donald Trump’s slew of victories on Super Tuesday has prompted a broad range of individuals and groups to take aim at his campaign for the White House. Among those proving the accuracy of the adage that politics makes strange bedfellows are the hacktivist collective Anonymous, former New Hampshire Gov. John Sununu and former Mexican President Vicente Fox.

Trump scored wins Tuesday in GOP presidential-nomination contests in Alabama, Arkansas, Georgia, Massachusetts, Tennessee, Vermont and Virginia. His success prompted several critics to take stands against the billionaire businessman.

President of Mexico between 2000 and 2006, Fox declared Trump to be a white supremacist.

“He’s gonna take this nation to the desert,” Fox said in a pretaped interview that will air on the Fox News Channel’s “Hannity” show Wednesday night. “He doesn’t understand about creating jobs. He only lies and lies and lies and uses whatever is convenient for him without any attention to facts. That’s why I say he’s an egocentric; he’s now only looking for himself and not for the rest. He believes in the white supremacy ... that’s Hitler.”

Other people such as Sununu have joined an anti-Trump super PAC, Our Principles. The former White House chief of staff under President George H.W. Bush said the super PAC wished it had mobilized efforts against Trump sooner.

“Donors feel guilty they didn’t get active earlier,” Sununu told the Associated Press Wednesday, adding, “Frankly, at this point we want anyone but Trump.”

Meanwhile, the hacktivist collective Anonymous has looked ahead to the possibility that Trump will be elected in November. “If Trump wins the election, we can only expect yet another generation of KKK members. We will be read. #OpKKK #HoodsOff,” the collective tweeted Wednesday in reference to the white supremacist Ku Klux Klan.
