President Barack Obama on Monday incorrectly stated that a landmark campaign-finance ruling allows foreign entities to pour money into U.S. elections. It's the second time he's made such a claim, and this time it happened while he was promoting the Democrats' DISCLOSE Act in a Rose Garden speech.

The Senate on Tuesday is taking up the legislation that would put strict new requirements on campaign advertising. The House already has passed a similar version of the bill.

"Tomorrow there's going to be a very important vote in the Senate about how much influence special interests should have over our democracy," Obama said. "Because of the Supreme Court's decision earlier this year in the Citizens United case, big corporations -- even foreign-controlled ones -- are now allowed to spend unlimited amounts of money on American elections."

Obama made a similar claim in his State of the Union Address, prompting Justice Samuel Alito to mouth the words "not true." The majority opinion itself and liberal commentators attested that Alito was correct
