Libertarian icon Rand Paul has beefed up his campaign store ahead of his announcement this morning that he would compete for the Republican nomination for president next year. Like Paul, the Kentucky senator who made a name for himself by championing issues not typically associated with the GOP such as criminal justice reform and privacy protections, much of the 'Rand' 2016 SWAG is unconventional. Rand fans will still find the usual array of yard signs and bumper stickers. But they'll also have the opportunity to sport their support through Macbook skins and woven blankets that feature Paul's face, 'Stand with Rand' flip-flops and car mats and a host of other unique items like the 'NSA Spy Cam Blocker.'The freshman senator beefed up his campaign store ahead of his presidential announcement this morningRand fans will find the usual array of yard signs and bumper stickers - but they'll also be able to sport their support with more unique itemsMacbook skins and woven blankets feature Paul, flip-flops and car mats bear the slogan 'Stand with Rand' and there's branded cornhole boardsFor $1,000 supporters can buy pocket Constitutions signed by PaulPaul's campaign store reflects the 52-year-old lawmaker's efforts to appeal to a new generation of conservatives

(CNN) The United States is trying to verify that an airstrike recently killed a high-ranking ISIS commander, and the Pentagon confirmed Wednesday that in a separate action it took out a commander of the Pakistani Taliban who was responsible for the deaths of more than 130 children. U.S. warplanes targeted senior ISIS operative Omar al-Shishani in Iraq in the past few days, some four months after the coalition first thought it had killed him in Syria, according to two U.S. officials. The United States is still trying to confirm they got him this time, the U.S. officials said. Al-Shishani, also known as "Omar the Chechen," was targeted by an airstrike near Qarayyah, Iraq, south of Mosul, the officials said. But they would not speak publicly until it's certain this time that he is dead. If he has been killed in Iraq, it's a sign that top ISIS operatives are still able to move around the region with some degree of freedom.U.S. thought it killed him months ago in SyriaKnown as "Omar the Chechen," he was one of ISIS' top commanders
