FILE — In this file photo taken April 4, 2013, marijuana plant starts are seen at a growing facility in Seattle. One of the U.S. Justice Department’s top concerns in allowing Washington and Colorado to move forward with plans to legalize and tax marijuana sales is seeing that the states keep criminals out of the industry. But the DOJ itself is refusing to let Washington run national background checks on those applying to run legal pot businesses, The Associated Press has learned, and those who have received the first legal pot licenses have done so without going through a national background check.
