Joe Biden is clearly growing tired of his daily task of having to think up responses to President Donald Trump’s increasingly erratic comments. Asked about Trump’s latest threat, when he blatantly refused to commit to a peaceful transfer of power if he loses the election fair and square, Biden rolled his eyes and sighed. Muffled behind his face mask, he said: “What country are we in?” Biden then briefly lowered his mask to say more clearly to the gathered reporters: “I’m being facetious—what country are we in? Look, he says the most irrational things. I don’t know to say.” During a White House briefing Thursday, Trump was asked if he has any intention of peacefully handing over power if he loses. The president ominously responded: “We’re going to have to see what happens.”
