I read/watched a number of news articles/videos on the subject and all reported it as Congress or the House of Representatives voting to hold Holder in contempt. 255 Republicans and 17 Democrats voted in favor of the contempt charge. All the articles mentioned the number of Democrats within a paragraph or two of the headline as well as the Democratic walkout. None phrased it as a solely Republican charge.
By the way, it "was" the Republicans and it "is" a Republican lead Congress. Talk about attempts to spin and paint a picture that is not true - you are trying hard, but failing.
Also, some person or persons are always slamming a liberal post by saying they never post facts to support their position. The OP posted no supporting source/facts to his assertions, I did.
