Republican Rep. Adam Kinzinger blasted President Donald Trump on Sunday night after the president quoted a Fox News contributor who warned of possible civil war if he is impeached.

The Illinois congressman, who is an Iraq War veteran, was the highest-profile Republican to criticize Trump, who Sunday night tweeted a quote by pastor Robert Jeffress earlier in the day on Fox News: “If the Democrats are successful in removing the President from office (which they will never be), it will cause a Civil War like fracture in this Nation from which our Country will never heal.”
