The President "earlier Thursday directed the Navy to return to steam-powered catapults and hydraulic systems on its Ford-class aircraft carriers, ditching the newer electromagnetic technology."

Sen. Mark Kelly of Arizona responds, "I've launched off the front of aircraft carriers hundreds of times, have a Master's degree in aeronautical engineering, and am a test pilot and even I wouldn't suggest to the Navy how to engineer specific systems on its ships."

The President "should stick to what he knows best — ballrooms, bankruptcy, and bulls---."
