CBS News Correspondent Scott MacFarlane posted this message on his social media.

It was a cryptic message, but he followed up with a link to a story in Variety, explaining why he was taking time off.

MacFarlane was covering former President Donald Trump’s rally in western Pennsylvania when he heard noises that reminded him of firecrackers. They were gunshots.

Suddenly, MacFarlane realized he was in potential danger — and a nearby rival was trying to keep him safe.

“Rachel Scott pulled me down,” says MacFarlane, referring to the ABC News veteran. She “grabbed me by the arm, told me to get beneath the bleachers.” On Sunday morning, MacFarlane tells Variety, “I gave her a big hug.”

MacFarlane says that he has been yelled at by Trump supporters.

“I can tell you I’ve noticed more people yelling at me over the past 24 hours,” MacFarlane says. “The language is fierce, more corrosive.” He’s heard people telling him that “I hope you die,” that “this is your fault.”

“That’s different than ‘fake news,’” he says.
