[aside]He was not, but still subject to criminal charges for making false statements:
Mr. Mandolfo. You should also understand that, although this interview is not under oath, that by law you are required to answer questions from Congress truthfully. Do you understand that? Mr. Archer. I do. Mr. Mandolfo. This also applies to questions posed by congressional staff during interviews. Do you understand that? Mr. Archer. I do. Mr. Mandolfo. Witnesses who knowingly provide false testimony could be subject to criminal prosecution for perjury or making false statements. Do you understand? Mr. Archer. I do.
I think all testimonies should be done this way. The idea that an oath would magically stop a liar from lying is silly. The only relevant thing is "if we catch you lying, you'll be in trouble."
