A person in the crowd during President Trump’s speech to the National Rifle Association on Friday threw what appeared to be a cell phone at the stage as the president approached the podium, according to video posted on social media.

The video, taken by attendee Bradley Brewer, shows the object being launched into the air and landing on the stage to Trump’s left. The speech took place in Indianapolis.

The person believed to have thrown the object was removed from the event, according to attendees.

“A man threw a cell phone on stage when President Trump walked out for his @nra speech,” tweeted Katie Pavlich, a Fox News contributor. “He threw it stage left, while POTUS was closer to stage right.”
