ST. PAUL, Minn. (AP) -- Minnesota lawmakers are considering reorganizing the state's Department of Human Services following a series of leadership resignations.

Commissioner Tony Lourey abruptly announced his resignation, followed by chief of staff Stacie Weeks. Two veteran deputy commissioners, Chuck Johnson and Claire Wilson, also resigned but rescinded their decision Wednesday.

Republican lawmakers who control the state Senate proposed a bill that would separate the department's office of the inspector general into its an independent agency. The office investigates claims of fraud and abuse.

Sen. Jim Abeler, R-Anoka, says the roughly 20-division agency is "just too big." He says there are deep problems in the department.

The $18 billion agency serves the welfare and foster care systems along with some seniors, people living with disabilities and sex offenders.
