The man accused of hiding out with a gun near Donald Trump's Florida golf course in an apparent bid to kill the former president wrote a letter months earlier describing an "assassination attempt" and offering a bounty on Trump's life, U.S. prosecutors said on Monday (September 23). Ryan Routh appeared at a hearing on Monday in which prosecutors will ask a judge to keep him in jail until his trial. In a court filing released before the hearing, prosecutors said that several months prior to the incident, Routh dropped off a handwritten letter addressed to "the world" that offered a bounty on Trump. Routh has been charged with two gun crimes. He has not yet entered a plea. Trump said that he will not make a fourth consecutive run for the U.S. presidency if he loses the Nov. 5 election, saying "that will be it" in an interview released on Sunday. Asked if he saw himself running again in four years if he is not successful in his third consecutive bid for the White House, the former president told Sharyl Attkisson's "Full Measure" program: "No I don't. I think that will be — that will be it. I don't see that at all. Hopefully, we will be successful." Israeli Prime Minister Benjamin Netanyahu said Israel faced "complicated days" as the armed forces shift their focus to the country's northern frontier, from where Hezbollah has been firing rockets into Israel in support of its ally Hamas. Netanyahu appealed for unity as Israel increases air strikes in southern Lebanon saying the operations were aimed at changing "the security balance, the balance of power in the north" after talking with commanders at military headquarters in Tel Aviv.
