Here is what Oklahoma's Senator Inhofe said about the use of filibuster against a judicial nominee. And not just on one occasion. It's unconstitutional.
And this is what he had to say yesterday:
Mr. President, it was my understanding earlier that I had about 15 more minutes than the 30 minutes that I understand are allotted me now. So if there is time at the end of my main message, I wish to address the problem of the David Hamilton nomination. In fact, I will announce that I will filibuster that nomination.
