Sen. Rand Paul, R-Ky., on Sunday warned against taking seriously comments his Senate colleague John McCain of Arizona made on Saturday, in which the Arizona lawmaker compared President Trump's actions toward the press to "how dictators get started."

"The thing is, I don't agree with his analysis and applying that to the president," Paul told Jon Karl, guest host of ABC's "This Week." "Everything that [McCain] says about the president is colored by his own personal dispute he's got running with President Trump and it should be taken with a grain of salt, because John McCain's the guy that's advocated for war everywhere. He would bankrupt the nation."

Paul, known for his noninterventionist foreign policy, also expressed relief that the 2008 Republican presidential nominee did not have a chance to act on his views as a commander in chief.

"And actually, we're very lucky John McCain's not in charge because I think we would be in perpetual war," Paul said.

Paul admitted Trump's comments during a Thursday press conference were "not something" he would have said, but he said Trump has a "distinct way" of expressing his opinion.

He added that Congress is not considering a bill that would take away the media's freedoms, despite McCain's warning.

Karl asked if John Bolton would make a good replacement as national security adviser for the recently fired Michael Flynn.

"I think John Bolton would be much closer to McCain than Trump and I think that his history of sort of acting on his own, my fear is that secret wars would be developing around the globe. So no, I think he would be a bad choice," Paul said.

While asked by NBC's "Meet the Press" host Chuck Todd about Trump's tweet bashing the media, McCain said, "If you want to preserve democracy as we know it, you have to have a free and sometimes adversarial press. Without it, I'm afraid that we would lose so much of our individual liberties over time. That's how dictators get started."
