The Republican Kentucky senator and possible 2016 presidential candidate tells a Hispanic business group that his message to the nation's illegal immigrants is: "If you wish to live and work in America, then we will find a place for you."

Coming off the 2012 election, many at the annual Conservative Political Action Conference are trying to figure out who can best return the party to White House power while upholding conservative principles. And Thursday, the young senators from Florida and Kentucky each made their case.

This annual gathering of conservatives is the first since President Obama thwarted Republican efforts to retake the White House, a defeat of Mitt Romney that many in the GOP didn't see coming. And while there will be some backward glances, the conference is mostly about finding the way forward.

The senator launched a nationwide conversation when he challenged the president's pick to lead the CIA. He vowed to keep talking until the White House clarified whether it has authority to kill U.S. citizens on American soil with drones. He finally stood down, but the debate is far from over.

Melissa Block talks to regular political commentators E.J. Dionne of The Washington Post and Brookings Institution, and Mary Kate Cary, former speechwriter for President George H.W. Bush and a columnist with U.S. °µºÚ±¬ÁÏ & World Report. They discuss the latest unemployment figures, Rand Paul's filibuster, and Jeb Bush.

The nomination survived an epic, nearly 13-hour filibuster by Sen. Rand Paul, who demanded an explanation of the Obama administration's targeted killing program.

"Does the president have the authority to use a weaponized drone to kill an American not engaged in combat on American soil?" the attorney general asks. "The answer to that question is no."

Paul's epic-length filibuster not only drew attention to an issue of increasing concern to Congress, but also helped raise his own profile. The Kentucky Republican has long been considered a presidential aspirant.

The senator said he "would speak, until I can no longer speak," and he hit that wall early Thursday. His goal was to get the Obama administration to pledge it won't use drone attacks against American citizens on U.S. soil. He's put a bright spotlight on the issue.

The Republican from Kentucky said he would speak until he could speak no more to sound the alarm on the Obama administration's targeted killing program.
