Special Counsel Robert Mueller's report is here, and pretty much no one knows what's in it.

The Justice Department announced Friday that Mueller had finished his investigation into potential ties between President Trump's campaign and Russian election interference. And within minutes, even the most unexpected lawmakers started calling for Attorney General William Barr to release it to the public.

First up came a wave of Democratic voices. House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer (D-N.Y.) issued a joint call for public report, while 2020 candidates chimed in with some variation on the theme. Sen. Chuck Grassley (R-Iowa) also surprisingly called for a public release, saying it was needed to "put an end to the speculation and innuendo that has loomed over the administration."

Those calls reflected a 420-0 House vote last week on a non-binding resolution to make the report public. Heck, even Trump said Tuesday that he wouldn't mind if Congress saw what Mueller had to say. But there's still one major holdout: Senate Judiciary Committee Chair Lindsey Graham (R-S.C.). In his Friday statement, Graham reflected Barr's language in simply calling for "as much transparency as possible, consistent with the law." Graham also blocked the House's popular resolution from a vote in the Senate earlier this week.

Grassley did pointedly note Friday that he was in Graham's committee position just last year — perhaps something he's regretting giving up right about now. Kathryn Krawczyk
