WASHINGTON, Jan. 26 (UPI) -- The 2016 presidential contest heated up as New Jersey Gov. Chris Christie launched a PAC and three senators debated before a group of conservative donors.
Marco Rubio of Florida, Ted Cruz of Texas and Rand Paul of Kentucky appeared at an event Sunday evening in Palm Springs, Calif., sponsored by Charles and David Koch. While it was unofficial, the debate moderated by Jonathan Karl of ABC had some of the trappings of a campaign appearance.
