John McCain: New block on defense policy bill is 'unfortunate'

Sen. John McCain sparred this week with the Democratic minority leader over bringing the annual defense authorization bill to the floor, but it was Republican Sen. Rand Paul of Kentucky who threw up the latest roadblock early Friday morning.

As the Senate was wrapping up its dramatic healthcare debate, Paul objected to a motion by Majority Leader Mitch McConnell, R-Ky., to move on to consideration of the $700 billion National Defense Authorization Act, which would have brought the must-pass bill to the floor.
