Martha Stewart said of Donald Trump: "We just can't have a country run by someone who is totally unprepared for what comes"

Donald Trump once publicly declared that Martha Stewart “lacked” the “temperament” to successfully host her Apprentice spinoff show, The Apprentice: Martha Stewart. Now she’s returning the criticism with some pointed words about her former business partner’s presidential campaign.

“There is so much to know and so much to learn and so much diplomacy and kindness and introspection that goes with that kind of job,” Stewart told CNNMoney on Sunday. “And it does not exist in the world of Donald Trump.”

The entrepreneur and business mogul added that she will vote for Democratic nominee Hillary Clinton in what Stewart described as “the most important election of the last hundred years.”

Stewart and Trump had a pubic falling out in 2006, after he wrote an open letter bashing her NBC Apprentice spinoff show, The Apprentice: Martha Stewart, for low ratings. Trump was an executive producer on the show.

Former Defense Secretary Robert Gates also criticized both Clinton and Trump’s lack of preparedness on foreign policy, though he said Trump is “beyond repair.”

“When it comes to credibility problems, though, Donald Trump is in a league of his own,” Gates, a Republican who served under Presidents George W. Bush and Barack Obama, wrote in a Wall Street Journal op-ed Friday.

“The world we confront is too perilous and too complex to have as president a man who believes he, and he alone, has all the answers and has no need to listen to anyone,” Gates wrote. “A thin-skinned, temperamental, shoot-from-the-hip and lip, uninformed commander in chief is too great a risk for America.”

Calling Trump “willfully ignorant about the rest of the world,” Gates continued, “At least on national security, I believe Mr. Trump is beyond repair. He is stubbornly uninformed about the world and how to lead our country and government, and temperamentally unsuited to lead our men and women in uniform.
