WASHINGTON (AP) — The House voted unanimously Thursday for a resolution calling for any final report in special counsel Robert Mueller’s Russia investigation to be made public, a symbolic action designed to pressure Attorney General William Barr into releasing as much information as possible when the probe is concluded.

The Democratic-backed resolution, which passed 420-0, comes as Mueller appears to be nearing an end to his investigation. Lawmakers in both parties have maintained there will have to be some sort of public resolution when the report is done — and privately hope that a report shows conclusions that are favorable to their own side.

Four Republicans voted present: Michigan Rep. Justin Amash, Florida Rep. Matt Gaetz, Arizona Rep. Paul Gosar and Kentucky Rep. Thomas Massie.

The resolution is unlikely to be passed in the Senate, where Democratic Leader Charles Schumer tried to bring it up hours after House passage. He was rebuffed when Senate Judiciary Committee Chairman Lindsey Graham objected. But the House vote shows that lawmakers from both parties are eager to have a look at Mueller’s findings after almost two years of speculation about what it might reveal.

Though Mueller’s office has said nothing publicly about the timing of a report, several prosecutors detailed to Mueller’s team have left in recent months, suggesting that the investigation is winding down. On Thursday, Mueller spokesman Peter Carr said in a statement that Andrew Weissmann, one of the most prominent prosecutors on the team, would be concluding his work “in the near future.”

The nonbinding House resolution calls for the public release of any report Mueller provides to Barr, with an exception for classified material. The resolution also calls for the full report to be released to Congress.

“This resolution is critical because of the many questions and criticisms of the investigation raised by the president and his administration,” said House Judiciary Committee Chairman Jerrold Nadler. President Donald Trump has repeatedly called the probe a “hoax” and a “witch hunt.”
