House Republicans united with their Democratic counterparts to pass a resolution demanding that the Department of Justice release to Congress, and then to the public the full report of special counsel Robert S. Mueller III.
"I hope this will be a bipartisan vote to tell the American people, you have the right to and ought to know the results of this report", House Majority Leader Steny Hoyer, D-Md., said on Thursday.
The special counsel's office has been busy with the probe since May 2017, investigating claims about the Trump's campaign colluding with Russian Federation and unlawfully attempting to obstruct the inquiry.
Four Republicans voted present: Michigan Rep. Justin Amash, Florida Rep. Matt Gaetz, Arizona Rep. Paul Gosar and Kentucky Rep. Thomas Massie.
Sen. Chuck Schumer of NY, the Democratic leader, tried to move the resolution through the Senate later Thursday by unanimous consent, but he was blocked by Sen.
"Transparency is fundamental to the special counsel's process, especially when dealing with matters of national security involving the president", said House Judiciary Committee Chairman Jerry Nadler, whose committee will oversee any impeachment motion.
Mueller and his team have been looking into possible crimes committed by the president or his associates, with a particular focus on whether or not they colluded with Russian interests during the presidential election of 2016.
Texas Rep. Will Hurd, a Republican member on the House Intelligence Committee who represents a swing district along the southern border, called on his colleagues to support "full transparency".
"I am especially concerned about what would happen if the report was not made available to Congress", Rep. Steve Scalise of Louisiana, the second-ranking Republican, said in a statement. The rules require him to notify the top Democrats and Republicans on the House and Senate judiciary committees after Mueller completes his probe.
At his Senate confirmation hearing in February, Barr was asked about sharing Mueller's report upon its completion.
House Democrats are prepared to use subpoena power and other tools at their disposal to force the Justice Department to turn over anything Barr chooses to withhold.
In February, six House Democratic committee chairs, led by Judiciary Chairman Jerry Nadler of NY, made a similar request in a letter to Barr.
It is anticipated that Mueller will soon finish his report and deliver it to Barr, who has not indicated whether he will make it public.
"I see this as the surest sign yet of a wrap-up", McQuade said.
