Convincing a single Democrat to sign on to a Republican tax bill is not achieving bipartisan support. This is bipartisan support.
In a Thursday morning vote, the House passed a non-binding resolution calling for the public release of special counsel Robert Mueller's final report to the attorney general by a vote of 420 to zip. Four Republicans did vote not-brave-enough-to-vote, including Trump’s Florida fixer Matt Gaetz and “Mr. No” of Kentucky, Thomas Massie … who apparently wasn’t willing to actually say no when people were paying attention.
Yes, it’s a non-binding vote. But actual legislation to this effect is working its way through the pipeline.
A similar bill would have likely passed in the Senate. It also had broad bipartisan support and was authored by Republican Chuck Grassley and Democrat Richard Blumenthal. However, Mitch McConnell blocked that legislation from coming to the floor. Because protecting Trump and keeping the nation ignorant is what McConnell is all about.
