Former South Carolina Gov. Mark Sanford is launching a political comeback that may begin within days.
Sanford is planning to run for the Congressional seat he held almost a decade ago, a Republican source familiar with his thinking told CNN late Thursday.
"He's looking all but certain to do it," said a former top aide to Sanford, who did not want to be identified while prematurely revealing the plans.
A formal announcement will come soon, the source said.
