Former Rep. Todd Akin (R-Mo.) nearly doubled the payroll of his office staff in the final quarter of 2012 as he ended his term in office.

In the last three months of the year, Akin paid his staff of 14 about $400,000, according to The Associated Press. Akin's quarterly payroll for the rest of the year averaged around $200,000. 

The salary increases were part of a "separation package" for staff who did not stay with the congressman because he lost his Senate campaign, Akin's former communications director, Steve Taylor, said Monday.
