CNN In Depth: Super PACs role in politics

As part of CNN’s In Depth series this week, Drew Griffin reports on the growing clout of political super PACs in U.S. elections.

On Anderson Cooper 360, Griffin interviews James Bopp, member of Citizens United which took the case of unlimited spending to the Supreme Court; Donald McGahn, FEC commissioner; and Foster Friess, a Rick Santorum super PAC backer.

Bopp says, “I think that we have made significant progress on restoring the central meaning of — and effect of the First Amendment.”

McGahn adds, “Control is impossible because courts have already said that they’re legal.  So there’s not much that the government can do to reign them in, so to speak.”

CNN In Depth will have more reports on Super PACs throughout the week .
