House Judiciary Committee Chairman Jerry Nadler, D-N.Y., led the charge Wednesday to hold Attorney General Bill Barr in contempt of Congress for not handing over documents related to Special Counsel Robert Mueller’s Russia probe -- declaring the move necessary as the country enters a "constitutional crisis." But Nadler took a very different stance on contempt back in 2012, when House Republicans took the same step against then-AG Eric Holder for refusing to hand over documents related to the Fast and Furious gun-running scandal, where DOJ officials tracked thousands of guns smuggled across the border but did nothing to stop them.
