It is unclear if KCNA was responding to a certain comment the former vice president made, though Biden went after President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

Biden also praised Trump in February after he walked away from a nuclear summit with North Korea, saying “He did the right thing by walking away. A bad deal is worse than no deal.”

The Biden campaign did not immediately respond to a request for comment from The Hill regarding KCNA's article.
