I for one am tired of judges giving stern rebukes that have zero teeth. Some for Grassley, Gowdy, and some others. They all talk a big game but steadfastly refuse to use the tools the constitution and law gives them.
talk talk talk.... like Charlie Browns teacher...
Contempt of Congress is voted on by the whole of the House or Senate. A committee or its chair doesn’t get to decide unilaterally.
Once again, this is at the feet of Ryan and McConnell.
