Alan Dershowitz: "You can't simply make statements about a subject and then plead the Fifth in response to questions about the very same subject.

You also cannot, after claiming the 5th and making a statement, answer a question from the chair and then just clam up.

You also cannot, after claiming the 5th and making a statement, answer a question from the chair and then just clam up.
