CHICAGO - President Barack Obama's chief of staff, Rahm Emanuel, was the congressman targeted by an alleged extortion plan described in the indictment against former Gov. Rod Blagojevich, according to attorneys familiar with the case.

At the time, in 2006, Emanuel was the congressman from the 5th District on Chicago's North Side. The attorneys spoke on condition of anonymity Thursday because the congressman isn't named and the information is secret grand jury material.

The indictment says the congressman sought a $2 million grant for a school. But Blagojevich allegedly told a lobbyist to tell the lawmaker his brother would have to raise campaign funds or the grant wouldn't go through.

Some of the funds were later released, even though no fundraiser had been held.

The White House declined to comment on the indictment.
