The Justice Department has moved to block a lawsuit from Missouri against the Food and Drug Administration (FDA) for allowing the abortion drug mifepristone to be shipped through the mail. The DOJ argues that allowing the suit to proceed would interfere with a safety study being conducted by the Trump administration. Missouri and several other Republican-led states have asked a judge to block an earlier policy that relaxed regulations for dispensing the abortion pill. The filing dismissed concerns from pro-life states that FDA policies allow abortionists to ship pills into their states. It also stated that states remain free to enforce their pro-abortion policies and that the federal government is not standing in the way of these states.
