One detail about President Obama's pre-Super Bowl interview Sunday that some viewers, maybe most, might have missed: He wasn't wearing a tie.

That didn't escape the discerning gaze of Donald Trump, though.

On "Fox and Friends" Monday, America's beloved game show host called Obama "sloppy" for the interview which was conducted by Bill O'Reilly.

"Frankly, I was impressed that the president agreed to do the interview with Bill," Trump said. "At the same time, I think he probably shouldn't have done it and I definitely think he should have worn a tie."

Trump continued: "You know? He's the President of the United States Let him put on a tie. Bill was wearing a tie, not that he has to follow Bill but Bill was wearing a tie. He's the president. It's a formal position. I think he should wear a tie."

F&F co-host Brian Kilmeade agreed. "That's a good point. I never thought of that," he said.

Asked to interpret Obama's fashion choice for the Super Bowl, Trump said it was "sloppy" and "not appropriate."

"He's the President of the United States," he said. "Let him put on a tie."
