Hand it to Jerry Nadler: He’s doing his best to blow enough smoke about supposed Team Trump crimes that it’ll still seem like there’s a fire somewhere.

As House Judiciary Committee chairman, Nadler has set a vote for Wednesday on whether to hold Attorney General William Barr in contempt for refusing to hand over the full, unredacted report from special counsel Robert Mueller or all the underlying materials behind the report.

Never mind that Barr by law can’t release grand jury testimony to the public. Or that Nadler and other committee members are free to view the report privately whenever they like. Or that handing over the complete Mueller files would be unprecedented.

Hey: Democrats need to insist that Barr is stonewalling or covering up . . . something.

“Congress must see the full report and underlying evidence to determine how best to move forward with oversight, legislation and other constitutional responsibilities,” Nadler claims — with “other responsibilities” meaning the impeachment that many Democrats expected to launch once Mueller finished up. Yet Mueller’s 448-page report exhaustively shows that there is zero sign of Team Trump collusion with Russia.

And while Mueller punted on declaring that Trump didn’t obstruct justice in all his raging about the investigation, he laid out the case that Dems would need to make to start impeachment proceedings over obstruction.

Access to Mueller’s files won’t give them anything more — it would only let them leak selected tidbits to fuel yet more anonymous stories smearing Trump & Co.

Barr is entirely right to nix that game, despite Nadler’s empty threats. (The 2012 vote by the full House to hold AG Eric Holder in contempt turned out to be utterly toothless.)

Which leaves Nadler reaching for another chance to gin up headlines: Having Mueller testify in hopes of getting something that might blacken Barr’s name, or Trump’s.

Years of media hysteria left the Democratic base addicted to “news” about Trump wrongdoing. Rather than face junkies gone cold turkey, Nadler & Co. keep cooking up more junk.
