Trump tweets about 'ghost guns'

The Trump administration may have permitted Texas-based nonprofit Defense Distributed to publish its 3D-printed gun blueprints to the internet, but that new reality has the president himself expressing some concerns, too. Democrats in New York and Washington, D.C., are taking note. U.S. Senate Democrats criticized the president for allowing Defense Distributed to publish its 3D printer files, even as they asked him to reverse his administration's decision.
