Gov. Pat Quinn has replaced the head of the Illinois Department of Transportation.

Quinn’s office announced Illinois Department of Veterans Affairs Director Erica Borggren has been appointed to the post held by Ann Schneider since 2011.

Quinn called Borggren a “proven leader,” but made no mention of why Schneider was departing from the agency that’s facing numerous problems. His office later confirmed her resignation is effective next week.

The state Senate must confirm the appointment.

Quinn’s hiring activities has come under scrutiny this year. Attorney Michael Shakman of Chicago wants a federal judge to order an investigation. The announcement comes on the same day Quinn ordered nearly half the state’s air fleet to be put up for sale, which Schneider was criticized for using frequently.
