To my recollection, Holder has not re-appeared on Capitol Hill, even to testify before the Senate, since he has been charged with Contempt of Congress.
The problem is that what this administration is doing is simply unprecedented. Nobody ever anticipated an administration that would behave in such a lawless fashion. As a consequence, there is no established approach toward addressing the problem.
Nonetheless, one would like to think that a serious-minded patriotic Republican leadership would at least make threatening noises...
I don't see where you get this idea. Did you read the Slate article?
In 1832, Sam Houston (that Sam Houston), then a private citizen, assaulted Ohio Rep. William Stanbery as Stanbery was walking home in Washington, D.C. According to Stanbery, Houston was indignant over something that Stanbery had said in a floor debate. Stanbery reported the assault to the House, which ordered its sergeant-at-arms to "take in custody, wherever to be found, the body of Samuel Houston; and the same in his custody to keep, subject to the further order and direction of this House." Houston was arrested and brought before the House, where he was represented by Francis Scott Key (that Francis Scott Key). After a monthlong trial, he was reprimanded and sent on his way.- - emphasis added

Sam Houston’s assault of William Stanbery occurred on Pennsylvania Ave, not within the Capitol.
