A federal appeals court on Friday refused to delay consideration of Timothy McVeigh's appeal in the Oklahoma City bombing, ruling he waited too long before raising a question about leniency agreements for prosecution witnesses.

McVeigh, who is appealing his conviction and death sentence, asked the judges to delay ruling on his appeal until they determined whether it was legal for prosecutors to offer leniency to criminal witnesses in exchange for testimony.But the 10th U.S. Circuit Court of Appeals said McVeigh's attorney should have raised the issue in an initial appeal brief or oral arguments, which occurred in April.
