This article makes it sound like Cooper beseeched Libby to grant a waiver when the fact is that Libby (like Rove) voluntarily signed waivers right off the bat.

Cooper was first subpoenaed to testify about Libby and refused despite the waiver (a little factoid omitted from this article). He in fact was held in contempt then and then cut a deal to give the Libby only testimony.

After he granted that the grand jury wanted the additional notes and testimony (which included the Rove conversation). Again he refused despite a long-standing waiver from Rove and again he was held in contempt until the 11th hour when he again agreed to grant the testimony after all and hence avoided jail.

That questioning took place in 2004. If you read the whole article you will see that the prosecutor had agreed to only ask questions about Libby. When Cooper's answers indicated there was another source for his information, he then refused to answer questions about that source. In his recent testimony to the grand jury, Cooper did reveal that source as Rove.
