Now, Andrew Weissmann, one of the top prosecutors with Special Counsel Robert Mueller, has derided the Clinesmith plea while actually calling on Justice Department attorneys to refuse to help on ongoing investigations that could implicate aspects of his own prior work.

I was among those who expressed concern when Mueller selected Weissmann due to his history of controversial prosecutorial decisions, including a pattern of prosecutorial overreach in the Enron litigation.

Weissmann's recent statements (made before the release of his new book on the Russian investigation) have only served to reaffirm those concerns.

Recently, Weissmann wrote an extraordinary and disturbing New York Times op-ed (with former Defense Department special counsel Ryan Goodman). In the column, he appeared to call on Justice Department lawyers to undermine the Durham investigation as well as the investigation by U.S. Attorney John Bash's investigation into the "unmasking" requests by Obama administration officials. They wrote "Justice Department employees in meeting their ethical and legal obligations, should be well advised not to participate in any such effort."
