NBC reports that a suspicious person was received an hour before a gunman opened fire at former President Donald Trump, a senator said. U.S. officials learned of an alleged Iranian plot to kill Trump weeks before the attempted assassination in Butler, Pennsylvania, sources said, adding that nothing indicated the two were connected. The Department of Homeland Security said its inspector general would investigate the Secret Service's security operation at Saturday's rally. Secret Service Director Kimberly Cheatle said that "the buck stops with me" and that the assassination attempt Saturday "should have never happened." That is to say, there are all kinds of threats to Trump's security. But why isn't enough being done to protect it? When Trump wins the election, will the Secret Service really take care of his security? Or are you going to continue ignoring reports and threats to your life? Do some groups want him dead and don't even bother to hide it? That is to say, it is obvious that they want it, but are there no plans to stop an assassination that is announced without any shame?
