In an article about Republicans who were offended by Trump’s latest gaffe (criticizing the Khans), an even more astonishing bit of Trump ignorance popped up:

Sen. Lindsey O. Graham (R-S.C.), who urged Republicans to walk away from Trump after the [Judge] Curiel episode, said the Republican nominee’s attack on the Khans is unprecedented.

“This is going to a place where we’ve never gone before, to push back against the families of the fallen. There used to be some things that were sacred in American politics — that you don’t do — like criticizing the parents of a fallen soldier, even if they criticize you,” Graham said. “If you’re going to be leader of the free world, you have to be able to accept criticism. Mr. Trump can’t.”

Mike Coffman, a veteran and Republican congressman from Colorado who has not endorsed his party’s nominee, said in a statement: “Having served in Iraq, I’m deeply offended when Donald Trump fails to honor the sacrifices of all of our brave soldiers who were lost in that war.”

A campaign spokeswoman for Sen. Rob Portman (R-Ohio), who is locked in a tight re-election battle and has only tepidly supported Trump, said Portman does not agree with the Republican nominee and called Khan a hero.

This was not the first time Trump has made controversial comments about the U.S. military.

Trump said that the nation’s armed forces are a “disaster” during a debate, in response to a question about military spending. He said Sen. John McCain (R-Ariz.), a former prisoner of war, was not a war hero because he was captured. And he has been attacking retired Marine Gen. John Allen, who spoke at the Democratic convention, for failing to defeat the Islamic State.

Trump also drew criticism Sunday when he appeared to be unfamiliar with Russia’s actions regarding Ukraine and its 2014 annexation of Crimea.

“He’s not going into Ukraine, okay,” Trump said on ABC’s “This Week” of Russian President Vladi­mir Putin. “He’s not gonna go into Ukraine, all right? You can mark it down. You can put it down.”

Trump then appeared to contradict himself when George Stephanopoulos, host of ABC’s “This Week,” responded that “he’s already there, isn’t he?”

“Okay, well, he’s there in a certain way,” Mr. Trump replied.

Trump’s comments were notable following his urging of the Russian government to meddle in the presidential election by finding tens of thousands of Clinton’s emails. U.S. officials said there is strong evidence Russia was involved in a hack of emails and voice mails at the Democratic National Committee.

In a statement, Jake Sullivan, the chief policy adviser for Clinton’s campaign, said that “this is scary stuff.”

“What is he talking about?” Sullivan wrote. “Russia is already in Ukraine. Does he not know that? What else doesn’t he know?”
