CHICAGO--Former Gov. Rod Blagojevich's lawyers asked a federal judge today to force President Obama to testify at Blagojevich's upcoming corruption trial, asserting that Obama played more of a role in the process of selecting someone to replace him in the U.S. Senate than Obama has acknowledged.
On the day before he was elected president, then-Sen. Obama personally called a union official about his desire for Blagojevich to appoint Obama adviser Valerie Jarrett to replace him in the Senate, according to Blagojevich's defense filing in U.S. District Court in Chicago.
