WATCH: Deranged Protester Throws Cell Phone at Trump During NRA Speech

On Friday, as President Trump spoke at the NRA convention in Indianapolis, a man was removed by the Secret Service after tossing a cell phone onto the stage as the president approached the podium.

The incident was captured on video, and while details remain scarce, Trump appeared to take the incident in stride, briefly smirking as he prepared to speak.

“Under my administration, we will never surrender American sovereignty to anyone,” Trump told the roaring crowd. “We will never allow foreign bureaucrats to trample on your Second Amendment freedoms.”

President Trump recently announced the withdrawal from the Obama-backed United Nations Arms Trade Treaty, which would have regulated US gun owners and manufacturers under European gun laws.
