Former President Donald Trump said on social media he was “shot with a bullet that pierced the upper part of my right ear” when shooting erupted at a campaign rally in Butler, Pa., Saturday. The Secret Service shot and killed a suspected gunman.

Federal authorities are investigating the shooting as an assassination attempt.

One spectator was killed and two others were critically injured after “multiple shots” were fired, the Secret Service said on social media.

Details on the suspected shooter weren’t immediately available.

The gunman used a rifle and fired from an elevated position outside of the rally, the Secret Service added.

President Biden spoke to the former president and is returning to Washington from Rehoboth Beach, Del.

Earlier, Biden declared there is “no place in America for this sort of violence. It’s sick.”

Messages of concern and support for Trump poured in immediately from top Democrats and top Republicans as well as former presidents—all decrying political violence.

Some Republicans blamed the shooting on Biden’s rhetoric; but Trump said motive is not clear.
