CHICAGO, Illinois (CNN) - FBI agents arrested Democratic Illinois Gov. Rod Blagojevich Tuesday on federal corruption charges, the U.S. attorney's office said.
The governor's chief of staff, John Harris, was also arrested on corruption charges.
The government says the two were "conspiring to obtain personal financial benefits" for the Illinois governor by leveraging his authority to appoint a U.S. senator. Blagojevich has the sole power to appoint a successor to the senate seat being vacated by President-elect Barack Obama. The U.S. attorney alleges Harris and Blagojevich are "engaging in ongoing criminal activity."
