U.S. Sen. Rand Paul promised to be a different kind of Republican on Tuesday, launching a 2016 White House bid by saying he would stand up for individual freedoms that are being trampled by ¡°the Washington machine.¡±

The first-term senator from Kentucky, a libertarian with a reputation for challenging party orthodoxy, criticized Republicans in Congress and the White House for helping to drive up the federal debt and reducing personal liberties.

¡°The Washington machine that gobbles up our freedoms and invades every nook and cranny of our lives must be stopped,¡± he told cheering supporters on a flag-draped stage in Louisville, Kentucky.
