New bodycam footage: moments before Trump rally shooting

The new footage suggests a local Pennsylvania police office told Secret Service to secure the building were former President Trump's would-be assassin fired off his rifle. The footage came from the bodycam of a Butler Township police officer. It also suggests that shooter may have used a wooden pallet to scale the building before he allegedly tried to assassinate the Republican presidential nominee at a campaign rally last month.
