President Trump’s former campaign adviser Roger Stone spent Labor Day vilifying John McCain in a pair of social media posts, denouncing the recently deceased Arizona senator as treasonous and corrupt.

Mr. Stone lashed out at McCain in separate Instagram posts Monday, a day after the Vietnam War veteran and lawmaker was laid to rest at the U.S. Naval Academy in Annapolis, Maryland.

“Enough already,” Mr. Stonecaptioned a photograph he shared on Instagram of a People magazine issue honoring McCain. “I knew John McCain Well since he was In the House. A bitter cranky and vengeful man responsible for the death of 134 servicemen in on the Deck of the USS Forrestal and as corrupt as the come,” Mr. Stone wrote.

“John McCain was epically corrupt, and a cranky mean spirited p—k,” Mr. Stone wrote in a subsequent Instagram post captioning a photograph of an article published by The New York Times. “His passing of the Russian dossier to the FBI was a fraudulent act of treason and he will get his just reward from his maker,” he added.

Months before being captured in Vietnam and held for years as a prisoner of war, McCain survived a fire that killed over 100 fellow service members stationed abroad the USS Forrestal aircraft carrier in the Gulf of Tonkin. McCain’s critics have smeared him as being complicit in the tragedy, but fact-checking sites including Snopes have found those claims to be false.
