Hearings on the Libby case will take place next week, via TPM Muckraker [1]:

On Capitol Hill, House Judiciary Chairman John Conyers (D-MI) has already called for hearing next Wednesday at noon titled "The Use and Misuse of Presidential Clemency Power for Executive Branch Officials." According to a committee aide, the hearing will have an eye to the future as much as the past. President Bush thinks jail time is "excessive" for an administration official convicted of lying to protect higher administration officials. In his statement announcing the hearing, Conyers worried about such a precedent: "Taken to its extreme, the use of such authority could completely circumvent the law enforcement process and prevent credible efforts to investigate wrongdoing in the executive branch." The aide told me that potential witnesses for the hearing include legal scholars, pardon experts, and administration officials.
