Mayor Michael Bloomberg remains the sole donor to his super PAC, Independence USA, pitching in $2 million more to the group in February, new reports show.

The group spent nearly all of the money it brought in during the month in support of Robin Kelly or against Deborah Halvorson in the House special primary election to replace former Rep. Jesse Jackson Jr., in Illinois. With Bloomberg’s support, Kelly defeated the National Rifle Association-friendly Halvorson 52 percent to 25 percent.

His four checks to Independence USA in February bring his total contributions to the group to about $12 million. Bloomberg formed the group in October of 2012 to back candidates that support gun control reform, among other issues.
