Joe Biden announced Tuesday that the wife of late Republican Sen. John McCain, Cindy McCain, will endorse his presidential campaign.

McCain says the decision came in the wake of President Trump’s alleged remarks about U.S. services members reported by The Atlantic.

Democratic presidential nominee Biden said during a fundraiser, “Maybe I shouldn’t say it but I’m about to go on one of these Zooms with John McCain’s wife, who is — first time ever — is endorsing me because of what he talks about with my son and John’s who are heroes, who served their country, you know he said they’re losers, they’re suckers.”

Trump Refuted Charges By The Atlantic That He Insulted War Dead

According to The Atlantic, Trump called WWI U.S. soldiers buried in France “losers,” though the White House fully denies this happened.

“The Atlantic Magazine is dying, like most magazines, so they make up a fake story in order to gain some relevance. Story already refuted, but this is what we are up against. Just like the Fake Dossier,” Trump tweeted in early September after The Atlantic story was published.

After the Atlantic article – using four anonymous sources – was published at least 21 officials have denied Trump said any such thing.
