Fact Check: Obama's Biggest Truths and Burning Lies
Claim: Mitt Romney Fully Endorsed Arizona Immigration Law
False: President Obama claimed in the second debate that Romney once called Arizona's controversial immigration law S.B. 1070 "a model for the nation." In reality, Romney said he supported the state's E-Verify mandate, allowing employers to electronically verify a person's legal status, which was passed as part of a separate state law in 2007.
