Lindsey Graham bizarrely threatens to make impeachment trial a thorough investigation

On Fox News Monday evening, Sen. Lindsey Graham (R-SC) warned that if Democrats try to bring witnesses in the impeachment trial of former President Donald Trump, he and Senate Republicans will retaliate by bringing in a ton of witnesses of their own. "We'll want the FBI to come in," he said.

Commenters on social media seemed confused as to why Graham's promise was a threat — with many impeachment-supporting pundits suggesting they were fully on board with the idea of a comprehensive, bipartisan impeachment trial that reviews all the evidence and expert opinions before arriving at a conclusion on the former president's guilt or innocence.
