Indictment suggests Rahm, brother were victims of extortion attempt?

Politico reports:

Rahm Emanuel appears to have been a victim of one of the extortion attempts with which former Illinois Gov. Rod Blagojevich was charged tonight.

Patrick Fitzgerald's indictment refers to two incidents involving "Congressman A": In one, Blagojevich discusses approaching the unnamed congressman to broker a deal for Obama's Senate seat.

In another, unrelated, charge, Blagojevich in 2006 allegedly demanded that the congressman or his brother -- Emanuel's high-profile sibling is super-agent Ari Emanuel -- hold a fundraiser for the governor in exchange for releasing $2 million to support a publicly funded school.

Or is this Congressman Jesse Jackson Jr.?
