“Trumps ban!”? Yeah, okeedokee!
Yes, Trump's ban. Here is a tweet from Trump on the subject back in 2018:
Obama Administration legalized bump stocks. BAD IDEA. As I promised, today the Department of Justice will issue the rule banning BUMP STOCKS with a mandated comment period. We will BAN all devices that turn legal weapons into illegal machine guns.— Donald J. Trump (@realDonaldTrump) March 23, 2018
