In a Tuesday Facebook post , the former CBS News anchor says the GOP presidential nominee “crossed a line with dangerous potential” by launching “a direct threat of violence against a political rival.”

Rather also says “history is watching” those who denounce Trump’s comments, but continue to support the candidate.

Trump told Fox News on Tuesday night that he was simply referring to the power that voters hold.

Rather left CBS News in 2006 on bitter terms following criticism over a report on former President George W. Bush’s military service record that was based on questionable documents.
