Iowa Attorney General Tom Miller is objecting to a Trump administration legal settlement that would allow a Texas group to move forward with publishing technical plans for 3D printed guns, reports the Cedar Rapids Gazette. Miller intends to join a lawsuit filed in Washington state to block publication of the plans online by the group Defense Distributed. Miller also joined 20 other attorneys general in a letter to the Trump administration, saying the settlement is “deeply dangerous and could have an unprecedented impact on public safety.”
