And Here. We. Go!: Solyndra Executives Will Take The Fifth In Congressional Inquiry
What is the Fifth Amendment again? What is the actual situation in which you're permitted to invoke it?
Ah yes: You invoke your Fifth Amendment rights against self-incrimination when an official inquiry would compel you to yield evidence against yourself, which could be used against you in a criminal trial.
Lately no one says that anymore; they invoke it vaguely, speaking of their rights to keep silent "based on any part of the Constitution which might be relevant," or whatever, avoiding naming the Amendment whose protections are sought.
In the letters sent to the House Energy and Commerce Committee's Subcommittee on Oversight and Investigations, attorneys for Solyndra CEO Brian Harrison and CFO W. G. Stover said they advised their clients not to provide testimony during the hearings.
