On this July 4th week, there are more than 80 members of the U.S. Congress calling for an impeachment inquiry into the crimes and misdemeanors of Donald Trump. So far, the two ranking members of Congress who could make that happen today, Nancy Pelosi and Jerrold Nadler, are resisting that pathway. Today, I interview Dr. John Gartner, contributing author to the 2017 bestseller “The Dangerous Case of Donald Trump” to find out why he believes that these members of Congress are correct and why the impeachment inquiry is necessary now.
