Sen. Marco Rubio (R-Fla.) said this morning on “Fox and Friends” that he doesn’t believe Donald Trump’s behavior is worthy of the office of the president.

Rubio said that a person must conduct themselves "in a dignified way with a level of class" in order to be president of the United States.

“I don’t think that the way he’s behaved over the last few weeks is either dignified or worthy of the office that he seeks. We already have a president now that has no class," he said.

Rubio remarked that President Barack Obama used a selfie stick in a BuzzFeed video, conducted an interview with a YouTube star who ate cereal out of a bathtub, and most recently joked about Iran on “The Daily Show.”

“It is important for us to have a presidency that restores dignity and class to the White House, and I don’t believe that some of the language that Mr. Trump is employing is worthy of the office,” Rubio said.
