Maryland Gov. Martin O’Malley’s political action committee dispatched and paid for a total of 32 staffers to aid candidates and state parties in Iowa, New Hampshire and other battleground states during the mid-term elections, his aides disclosed Sunday.

O’Malley (D), who is weighing a 2016 White House bid, gathered with many of the campaign workers at a lunch in Baltimore on Friday, but it is unclear how many will remain employed by his political operation. Spokeswoman Lis Smith said O’Malley is “still evaluating” how many of the 32 campaign workers to retain.

O’Malley has said he will probably decide by the end of his tenure as governor in January whether to move forward with a presidential run. Such a move would require him to significantly expand the small group of aides who are currently guiding his political activities. O’Malley has said he is preparing for a White House bid regardless of whether Hillary Rodham Clinton runs.

The Washington Post previously reported that O’Malley was hiring temporary staff to send to battleground states. On Sunday, aides disclosed for the first time the full list of candidates and party committees that received the assistance.

According to the list, O’Malley dispatched 14 staffers to Iowa, four to New Hampshire, four to South Carolina, four to Maryland, three to Nevada and one apiece to Kansas, Michigan and Wisconsin.

In most cases, the staff was sent to help Democratic party committees. In Iowa, however, O’Malley also dispatched campaign workers to aid the Democratic gubernatorial candidate, four congressional candidates and the secretary of state hopeful.
