Did Secret Services Know About Donald Trump's Assassination Plot, Eyewitness Claims Security Lapse

The attack on Trump was the most serious attempt to assassinate a president or presidential candidate since Ronald Reagan was shot in 1981. It drew new attention to concerns about political violence in a deeply polarized U.S. less than four months before the presidential election. Officials said the shooter was engaged by members of the U.S. Secret Service counterassault team. The heavily armed tactical team travels everywhere with the president and major party nominees and is meant to confront any active threats while other agents focus on safeguarding and evacuating the person at the center of protection. Trump flew to New Jersey after visiting a local Pennsylvania hospital, landing shortly after midnight at Newark Liberty International Airport.
