Well, unsure if this is directly attributable to Trump but from todays Reuters article :
"U.S. District Judge Robert Lasnik said the State Department violated federal law by letting Defense Distributed, a Texas-based nonprofit, publish downloadable blueprints for the untraceable, undetectable, mainly plastic firearms, as part of a June 2018 legal settlement.
Lasnik cited the State Department’s prior view that publishing such instructions could threaten U.S. foreign policy, national security and even world peace by enabling criminals, including terrorists outside the United States, to obtain the firearms.
“Against these findings, the federal defendants offer nothing” to support the reversal, the Seattle-based judge wrote. “Because the agency action was arbitrary and capricious, it is unlawful and must be set aside.”
The State Department is reviewing the decision. The U.S. Department of Justice, which represented the agency, did not immediately respond to requests for comment. "
and this also from the article :
"“It is baffling that the Trump administration continued to work so hard to allow domestic abusers, felons and terrorists access to untraceable, undetectable 3D-printed guns,” Washington state’s attorney general, Bob Ferguson, said in a statement.
He said Republican President Donald Trump tweeted one day after the July 2018 lawsuit was filed that he was looking into the public sale of 3-D guns and had spoken to the National Rifle Association, and said the guns did not “seem to make much sense!”
“I’m thankful the court agrees,” said Ferguson, a Democrat.
California, Illinois, Massachusetts, New Jersey, New York, North Carolina, Pennsylvania and Virginia were among the more populous states to join Ferguson’s lawsuit.
Defense Distributed had argued that the earlier ban violated its constitutional rights to free speech and to bear arms under the First and Second Amendments. It had hoped to make its blueprints available to the public in August 2018. "
What, the companies free speech has been curtailed ?? detailed plans for weapons qualifies ?? I think the 2nd amendment says, a citizen has a right to bear arms, as part of a well regulated militia [ nor is the word gun or firearm found in the amendment] . I suppose DefenseDistributed owners and employees are all part of the National Guard ? Because none of the 2nd amendment "boosters" that i'm acquainted with are in any sort of regulated militia....
