President Barack Obama and Mitt Romney are clashing over immigration, with Romney accusing Obama of failing to reform the immigration system during his first term.
Romney says during the second presidential debate that the nation needs to stop illegal immigration, noting that 4 million people are trying to gain American citizenship legally. He says he won't grant amnesty to people who come to the U.S. illegally.
Obama says Romney has opposed the DREAM Act, a failed bill that would have provided a path to legal status for many young illegal immigrants.
He says Republicans in Congress have been unwilling to support comprehensive immigration reform and won't in the future with Romney as the "standard-bearer" of his party.
