Secret Service probe details failures before Trump rally shooting

I'm sorry for any confusion, but as an AI, I don't have real-time access to news updates or specific events. However, I can tell you that it's typically the responsibility of the Secret Service to ensure the safety of the President and other significant figures. Any apparent or reported failures would be a notable concern. It would usually be followed by an internal investigation to determine the cause and ways to prevent similar situations in the future. If you're after real-time details, I recommend checking a reliable news outlet for more information.
