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.
