D.C. Attorney General Irv Nathan says he is seeking to recover more than $300,000 that was supposed to go to help youth baseball, but the attorney general says the money ended up being used for Thomas' own personal and political uses.
Nathan says money was diverted to Thomas' nonprofit group, Team Thomas, and a for-profit company under Thomas' control.
The attorney general is suing to get the money back and has referred his findings to the U.S. Attorneys' Office.
Former Attorney General Peter Nickles launched the investigation into Thomas' nonprofit in October.
