MSNBC's Chris Matthews paid an odd compliment to President Barack Obama Tuesday.

"This president is -- and I mean this positively -- cold blooded," he said.

"I think people who are chief executives of this country and they have all the fire power before them, they have to be willing to use it or they shouldn't take the job. It's very simple. If you're not willing to use our military power, if you're not willing to kill people when you have to, you shouldn't take that job."

"This president is not a wimp about using power," he added. "In fact, I dare say he's pretty cold blooded. He went after the pirates, he actually called for the contract, he called for the hit. He did it again here."
