A 58-year-old man detained Sunday in connection with an apparent assassination attempt on Donald Trump in Florida is a self-employed affordable housing builder in Hawaii who went on social media to weigh in on politics and current events, at times criticizing the former president.
Ryan Wesley Routh, who authorities suspect was planning to attack the former president as he played a round of golf, posted comments on an X account linked to him referencing the assassination attempt on Trump at a July rally in Pennsylvania.
Routh tagged Joe Biden and Vice President Kamala Harris, in separate posts, encouraging them to visit those injured at the rally. #Trump #CNN #News
