Gov. Tom Wolf said today that the state budget he proposes Tuesday will include two mergers intended to save money and improve the service of related missions. Wolf will renew his call to merge the Department of Corrections and the Board of Probation and Parole into a single agency.  A bill to combine the two entities passed the Senate back in November. He also will propose moving the eHealth Partnership Authority, which was created to enable the secure exchange of electronic health information, into the Department of Human Services.
