I watched the movie Miss Sloane.
This is the story of a lobbyist with convictions who goes to work for a firm trying to get passed a universal background check for gun sale bill through Congress.
However, along the way, Congress starts to investigate her for violating ethics rules and later it comes out that she planned this investigation and exposes that her prior firm and a leading Senator conspired to squelch the bill by investigating her.
I think that the writers of the movie were attempting to show that Congress had unreasonable powers of investigation and that the gun rights lobby is overly powerful.
I thought it was a good movie, although I assume that the writers were attempting to promote a liberal and anti-gun-sales agenda. However, I am not sure what position is best on the question of universal background checks.
