ORLANDO, Fla. — Newt Gingrich raised $5 million in January and revised up his fundraising totals for the fouth quarter of 2011 by $1 million, up to $10 million, his campaign said Tuesday.

Gingrich’s totals for the most recent fundraising period, which spanned October and December, are 10 times what he raised in the third quarter of 2011. But his fundraising still trails two of his opponents, former Massachusetts Gov. Mitt Romney and Texas Rep. Ron Paul.
