(CNN) – Former House Speaker Newt Gingrich spent a second day trying to campaign in Iowa but fending off questions about his relationship with mortgage giant Freddie Mac.
The former House Speaker has surged to the top of Republican presidential polls over the last month but is now forced to play defense against reports of his relationship with Freddie Mac. Gingrich Group was paid between $1.6 million and $1.8 million to lobby Republicans in Congress on behalf of the government-backed mortgage lender, CNN has confirmed.
Questioned about the reports on Wednesday in Urbandale, Gingrich said that his consulting company was paid by Freddie Mac for "strategic advice over a long period of time."
