What we know about suspect in Trump ‘attempted assassination’ [Video]

The suspect in what the FBI has called an “attempted assassination” of former President Donald Trump was a booster of a number of causes, ABC News analysis of his apparent social media profiles shows.

As authorities tried to unravel the motive and details of the case, sources said investigators were looking at whether Routh was frustrated with Trump’s position on Ukraine. Trump refused to answer when asked if Ukraine should win its war against Russia during the ABC News presidential debate last week.

Authorities recovered an “AK-47-style” rifle with a scope, two backpacks — one of which had a ceramic tile in it — and a GoPro from the scene, Palm Beach County Sheriff Ric Bradshaw said. The would-be gunman was within 300 to 500 yards of Trump when he was spotted. The former president was unharmed in the incident and it is unclear whether the suspect fired any shots.
