Gunfire appeared to erupt at former President Donald Trump’s rally in Pennsylvania while he was speaking on stage — and he was grazed in the ear, law enforcement said.

What sounded like gunshots rang out just about five minutes into his speech shortly after 6 p.m., sending Trump to the ground as Secret Service agents jumped in to cover him.  Sources said the investigation is ongoing and they are looking into if the shots were from a BB gun.

Donald Trump has said in a statement that he is “fine” and that he is being checked at a medical facility.

The former president raised his fist as he was being rushed off the stage by his Secret Service detail.
