"What this really is is misplaced criticism of [William] McRaven," Clapper said on "CNN Right Now."

"It's really a slam at the intelligence community, who was responsible for tracking down Osama bin Laden, and reflects, I think, his complete ignorance about what that took."

The president also questioned why it took so long for the U.S. to find bin Laden, who was ultimately killed by Navy SEALs in a 2011 operation in Pakistan.

"Wouldn’t it have been nice if we got Osama bin Laden a lot sooner than that, wouldn’t it have been nice?" Trump said Sunday.

Trump's comments drew swift backlash, with retired Lt. Gen. Mark Hertling calling his attack on McRaven "disgusting" and multiple U.S. lawmakers releasing statements to convey their support of the ex-Navy SEAL.

McRaven responded to the president's comments shortly after by doubling down on his previous criticism of Trump. McRaven said Trump's attack on the media represented "the greatest threat to our democracy in my lifetime."

"When you undermine the people's right to a free press and freedom of speech and expression, then you threaten the Constitution and all for which it stands," he said in a statement, adding that he did not support Democratic presidential nominee Hillary Clinton during the 2016 presidential election.

The president defended his stance on Monday, tweeting that the U.S. "should have captured Osama Bin Laden long before we did."
