Trump tells British Prime Minister Cameron "I'm not stupid, okay?"

The ongoing feud between the British and Donald Trump just stepped up another level.

In an interview scheduled to air Monday with Piers Morgan, the Republican candidate for president is already talking about his foreign relations before general election ballots have even been cast. Given past comments from Cameron calling Trump "stupid, divisive and wrong," Trump thinks they're unlikely to have a great relationship, according to the Jerusalem Post.

"It looks like we're not going to have a very good relationship. Who knows! I hope to have a good relationship with him but it sounds like he's not willing to address the problem either," Trump said in the interview. "I hope to have a good relationship with him but it sounds like he's not willing to address the problem either."

"Well, number one I'm not stupid, Okay. I can tell you that, right now - just the opposite. Number two, in terms of divisive: I don't think I'm a divisive person. I'm a unifier, unlike our president now (referring to President Barack Obama), I'm a unifier," Trump continued.
