Is Donald Trump actually just a Democrat sleeper agent designed to make the Republican Party look bad?
It would certainly explain a lot about the businessman-turned-politician, whose recent gaffes include tweeting an image of Nazi soldiers inside the US flag and calling Mexican immigrants to America rapists and drug dealers.
Carlos Curbelo, a Republican congressman from Florida, apparently thinks it is possible.
He was quoted by the Miami Herald as saying Trump is "quite possibly... a phantom candidate recruited by the left to create this entire political circus".
Curbelo actually seems to be serious about the theory, pointing out in a radio interview given in Spanish and translated by the Miami Herald: "Mr Trump has a close friendship with Bill and Hillary Clinton. They were at his last wedding. He has contributed to the Clintons' foundation. He has contributed to Mrs Clinton's Senate campaigns. All of this is very suspicious."
On Wednesday morning Donald Trump discussed the claim on Fox and Friends insisting he was not a mole for the Democratic Party. Referring to himself in the third person, he said: "Believe me - from Hillary's standpoint, the one person she doesn't want running against her is Donald Trump." As for his contributions to the Clinton foundation? "I’m a businessman, I contribute to everybody... That’s part of the problem with the system."
