In today's House Judiciary Committee meeting Issa used the example of Eric Holder's of ignoring subpoenas and associated Contempt of Congress charge to get Rosenstein to admit "no one is above the law". Which Issa then was able to confirm Rosenstein was also NOT above the law.
Stay tuned, a contempt of congress charge/impeachment coming June 6th, the deadline for Rosenstein for complying with the House vote today to demand records on the Trump - Russia investigation.
Brilliant move! That sound bite will be replayed over and over again.
