Solyndra executives repeatedly invoked the Fifth Amendment  this morning as House lawmakers pressed them to answer questions about the company's financial collapse and any hopes of repaying their $535 million federal loan guarantee.

"While I hope to have an opportunity to assist this committee in the future, on the advice of my attorney, I must respectfully decline to answer any questions," Solyndra CEO Brian Harrison told Energy and Commerce oversight subpanel Chairman Cliff Stearns (R-Fla.), who opened the questioning.

CFO Brian Stover gave a similar response.

The repeated questions drew an objection from Rep. Henry Waxman (D-Calif.), who slammed Republicans for persisting even after knowing that the executives would invoke their right to remain silent.
