Huge news out of Chicago this morning:

CHICAGO (AP) — An official says Illinois Gov. Rod Blagojevich (bluh-GOY’-uh-vich) has been arrested in Chicago on corruption charges stemming from the selection of the successor to President-elect Barack Obama’s U.S. Senate seat.

U.S. Attorney’s office spokesman Randall Samborn says both Blagojevich and his chief of staff John Harris were arrested Tuesday. Authorities aren’t yet releasing details about those charges. However, a federal law enforcement official tells The Associated Press the governor is accused of corruption charges. The official says the charges stem from the selection process of a successor to Obama.

Federal prosecutors have investigated Blagojevich’s administration for at least three years. They’ve been looking at everything from how he hired people for state jobs to the actions of friends and contributors.

More to come, I’m sure.

Update: Further details from The Chicago Tribune:

Gov. Rod Blagojevich and his chief of staff, John Harris, were arrested by FBI agents on federal corruption charges Tuesday morning.

Blagojevich and Harris were arrested simultaneously at their homes at about 6:15 a.m., according to Frank Bochte of the FBI. Both were awakened in their residences and transported to FBI headquarters in Chicago.

In one charge related to the appointment of a senator to replace Barack Obama, prosecutors allege that Blagojevich sought appointment for himseld as Secretary of Health and Human Services in the new Obama administration, or a lucrative job with a union, in exchange for appointing a union-preferred candidate.

Another charge alleges Blagojevich and Harris conspired to demand the firing of Chicago Tribune editorial board members responsible for editorials critical of him in exchange for state help with the sale of Wrigley Field, the Chicago Cubs baseball stadium owned by Tribune Co.

Blagojevich and Harris, along with others, obtained and sought to gain financial benefits for the governor, members of his family and his campaign fund in exchange for appointments to state boards and commissions, state jobs and state contracts, according to the charges.

“The breadth of corruption laid out in these charges is staggering,” U.S. Attorney Patrick Fitzgerald said in a statement.

“They allege that Blagojevich put a ‘for sale’ sign on the naming of a United States senator; involved himself personally in pay-to-play schemes with the urgency of a salesman meeting his annual sales target; and corruptly used his office in an effort to trample editorial voices of criticism.”

Blagojevich is scheduled to appear before U.S. Magistrate Judge Nan Nolan later today, according to Randall Samborn of the U.S. attorney’s office.

Apparently, Barack Obama’s Senate seat was put up for sale by the Governor of Illinois. Notwithstanding my generally bad opinion of politicians, this one is absolutely staggering and it’s unclear right now what the political implications of all this are going to be.
