Trump is proving once again that, no matter how disgusting his behavior, he will never hesitate to push the blame onto someone else.

After spending the last two days trying to deflect and lie his way out of ignoring the deaths of four U.S. soldiers in Niger, Donald Trump fanned the flames by calling up Sgt. La David Johnson’s pregnant widow, Myeshia Johnson, to say her husband “knew what he signed up for.”

Trump’s complete lack of empathy, and ignorance of both how the military works and his own responsibilities to our servicemen as commander in chief, caused howls of outrage.

Making matters worse, as Myeshia told her congresswoman, Rep. Fredericka Wilson, Trump did not even know her husband’s name when he called her.

But on Wednesday morning, instead of mustering the tiniest scrap of human decency that would be necessary to own up to his bad judgment and apologize, Trump doubled down and attacked Wilson for bring these facts to light, calling her a liar:

This is essentially the worst possible thing Trump could be doing right now. He is besmirching not only Wilson’s integrity, but Myeshia’s — effectively daring an Army widow to publicly come out and make it her word against his:

Trump has had every opportunity over the past few days to take some personal responsibility and show some compassion. At every single turn he has simply tried to pass off his own failings onto others — including a pregnant mother of two who just lost her husband.

There is simply no redeeming this man, or this presidency. Trump is bereft of even a pretense of moral credibility and can no longer hope to unify the nation in any capacity. And any Republican who rushes to his defense no longer has any acceptable excuse.
