Wednesday was former White House press secretary Jay Carney's first night as a CNN commentator, so the network did the nice thing and brought John McCain on to yell at him for a while about President Obama's speech on ISIS. Since McCain loves both TV and arguing, it made for a lengthy brawl. Carney mostly kept his cool and defended his former boss as McCain accused him of lying about lots of things. It ended when McCain left to appear on every other television channel on earth.
