This Mark Zaid (of Compass Rose) has some connections to Dr Meryl Mass, the Cuban trained gal who along with another woman. Rosenberg, was called by Pelosi and friends to testify in kangaroo hearings on the Amerithrax case back when the Dems were trying to push Mueller to go after Stephen Hatfill for the anthrax letters.
Nass is always against anything that might thwart Cuban schemes, such as vaccines against biological weapons that are within Cuban capabilities to produce. Either a spook or a wannabe.
