Asked by a reporter about Khashoggi's murder during a press conference in the Oval Office, Trump defended the crown prince -- who minutes earlier had pledged to increase his past commitment of $600 billion in investments in the U.S. to $1 trillion. "He's done a phenomenal job," Trump said of Mohammed, adding: "Things happen, but he knew nothing about it." And, referencing Khashoggi, the president also seemed to offer an explanation for his murder: "a lot of people didn't like that gentleman," he said.
