Back and forth they go.

The president and the decorated Navy SEAL are at each other’s throats. I’m pulling for the SEAL.

Donald Trump — as is his tendency — fired off a totally inappropriate tweet challenging whether the head of the U.S. Special Operations Command could have taken out Osama bin Laden “sooner” than he did.

That commander is retired Admiral William McRaven, on whose watch U.S. commandos killed the 9/11 mastermind in a firefight in Pakistan.

McRaven had the temerity to declare that Trump’s attack on the media presents the “greatest threat” to the nation. Trump responded with that hideous Twitter taunt about the bin Laden raid.

McRaven has answered the president. He stands by his comment about Trump’s attack on the media. Trump also had accused McRaven of “backing” Hillary Clinton. McRaven said “no.” He isn’t a fan of the former Democratic presidential candidate. He also said he backs all presidents, because he respects the office. McRaven also notes in his response that he served under Presidents George W. Bush and Barack Obama while leading the Special Operations Command.

He told Trump, “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.”

If only the president understood the damage he does with his reckless and feckless rhetoric.
