State Comptroller Susana Mendoza is asking legislators to require the governor’s office to pay employee salaries from its own budget instead of “off-shoring” the costs to agencies.

According to Mendoza, Gov. Bruce Rauner has an office budget of $4.9 million, but he’s actually spending $10.4 million. The comptroller’s staff can decipher the practice known as off-shoring by pay codes which identify account sources.

Rauner spokeswoman Rachel Bold said the governor is open to “changing bookkeeping practices.”
