EAST ST. LOUIS • A man from Southern Illinois sued President Donald Trump and two other federal officials Wednesday, claiming that last month’s ban on bump stocks and similar devices was unconstitutional.

The suit also seeks to represent the owners of an estimated 500,000 or more bump stocks and win them compensation of between $125 million and $250 million if the devices have to be destroyed or turned in.

The suit was filed in U.S. District Court in East St. Louis by a man who sued as a “John Doe,” saying that if he used his real name, he could be arrested and prosecuted for continuing to possess “one or more bump stock and/or bump firing devices.”

The devices attach to a rifle and use the recoil of an initial shot to allow the weapon to fire continuously.

In addition to naming Trump, who ordered the ban, it names acting Attorney General Matthew Whitaker and Thomas E. Brandon, acting director of the Bureau of Alcohol, Tobacco, Firearms and Explosives.
