Former House Speaker Newt Gingrich (R-Ga.) is looking to stake out some of Rep. Ron Paul's (R-Texas) political turf with his push this week for an audit of the Federal Reserve.

Gingrich, a rival of Paul's for the 2012 Republican presidential nomination, has co-opted the Federal Reserve audit Paul had fought for during last year's Wall Street reform battle, and made it a centerpiece of his campaign.
