Peanut company owner refuses to testify

Peanut company owner refuses to testify: "Parnell sat stiffly, his hands folded in his lap at the witness table, as Rep. Greg Walden, R-Ore., held up a clear jar of his company's products wrapped in crime scene tape and asked him if he would be willing to eat the food.
'Mr. Chairman and members of the committee, on advice of my counsel, I respectively decline to answer your questions based on the protections afforded me under the U.S. Constitution,' Parnell said."
