Citizens United v. FEC

A very big case has been argued in front of the Supreme Court:

In Citizens United v. Federal Election Commission, the Deputy Solicitor General of the United States of America asserted that the U.S. Constitution would allow the government to ban commercially published books that contain the phrase “Vote for Candidate X” close to an election!

...Again and again, your government emphatically asserted the Constitution permits it to ban the commercial publication and marketing of a book and to throw that publisher in jail for up to five years if the book includes a single phrase that expressly advocates for the election or defeat of a federal candidate. This is precisely the kind of government encroachment that the First Amendment is suppose to protect us against. What comes next? Banning activists from holding signs at protests in front of the White House that mention a President who is up for re-election? Unbelievably, the government lawyer claimed that they could ban that too if the sign was funded by a corporation.

I guess that's why they are also in favor of banning the private ownership of guns.
