Rep. Michele Bachmann on Saturday stood by her claim that Newt Gingrich supports “amnesty” for illegal immigrants, digging up a letter the former House speaker signed nearly eight years ago to combat claims that she was misrepresenting his plan.

Gingrich, after saying at a Republican presidential primary debate that the U.S. should afford some illegal immigrants a pathway to legal status, has clarified that he only wants to open that door for some illegal immigrants who have been in the country 25 years or more.
