In an exclusive interview, Sen. Patrick Leahy, D-VT, chairman of the Senate Judiciary Committee, said that any reform of the Miranda warning – which informs criminal suspects of their Constitutional rights – to better deal with terrorism suspects must fall within the bounds of Supreme Court precedent.

"It was the Supreme Court that set down the rules of Miranda," Leahy told host Jake Tapper. "Whatever changes might be made, has to made within the confines of what the United States Supreme Court has already said."

Leahy said that "you have to have maximum flexibility within the rules, but the idea that you're going to be able to pass a statute to change the Constitutional ruling of the Supreme Court, you can't do that."
