President Barack Obama says the nation should consider mobilizing behind a constitutional amendment process to overturn the Supreme Court ruling that loosened restrictions on money in politics.

Obama made the comment Wednesday in an online chat with the website Reddit. The 2010 Citizens United ruling paved the way for a flood of campaign cash from corporations, unions and wealthy interests.

The president says that even if the amendment process fell short, "it can shine a spotlight" on super PACs and, in his words, "help apply pressure for change."

Obama says that in the meantime there's a need for more disclosure of the large campaign contributions flowing into super PACs and that such contributions, quote, "fundamentally threaten to overwhelm the political process."
