Man suspected of assassination attempt against Trump left a letter detailing his plans, prosecutors say

In a court hearing, prosecutors also said they plan to charge Ryan Wesley Routh with attempting to assassinate Trump, and a federal magistrate judge ordered Routh to remain detained pending further proceedings.
