What is most troubling about Mr. Putin's aggression in Crimea is that it reflects a growing disregard for America's credibility in the world. That has emboldened other aggressive actors - from Chinese nationalists to Al Qaeda terrorists and Iranian theocrats.

In 1987, I had my first opportunity to provide 'advice and consent' on a Supreme Court nominee. At that time, I stated that the qualifications essential for evaluating a nominee for the bench included 'integrity, character, legal competence and ability, experience, and philosophy and judicial temperament.' On that test, Elena Kagan fails.

My record shows that I have put my country first, and I follow the philosophy and traditions of Abraham Lincoln and Theodore Roosevelt and Ronald Reagan.

I think it's important for the president of the United States to be aware of the intelligence information that we have.

I am proud to perform at the Nobel Peace Prize Concert.

Any American who joins al Qaeda will know full well that they have joined an organization that is at war with the United States.
