Shouldn't former federal judge Mark Fuller now be federally prosecuted for perjury?

The question in the title of this post prompted by this new AP article, headlined "Judicial Conference says former federal judge's conduct was reprehensible, impeachable." Here are the details:

Judicial investigators told Congress this week that a former federal judge — arrested last year on a domestic violence charge — had demonstrated "reprehensible conduct" and there was evidence that he abused his wife several times and made false statements to the committee reviewing his behavior.

The Judicial Conference of the United States, in a report to Congress this week, said former U.S. District Judge Mark Fuller of Alabama brought disrepute to the federal judiciary and that his conduct might have warranted impeachment if he had not resigned this summer.  

In a letter to the House Judiciary Committee [which can be accessed here], the Judicial Conference noted Fuller's resignation, but said the severity of Fuller's misconduct and its finding of perjury led it to turn the information over to Congress for whatever action lawmakers deem necessary. "This certification may also serve as a public censure of Judge Fuller's reprehensible conduct, which has no doubt brought disrepute to the Judiciary and cannot constitute the 'good behavior' required of a federal judge," Judicial Conference Secretary James C. Duff wrote in a Sept. 11 letter to House Speaker John Boehner....

The Judicial Conference wrote that there was substantial evidence that the judge "physically abused Kelli Fuller at least eight times, both before and after they married, which included and culminated in the assault that took place on Aug. 9, 2014, in the Ritz-Carlton Hotel in downtown Atlanta, Georgia." The conference wrote that Fuller denied under oath to the investigating committee that he ever hit, punched or kicked his wife, and that the investigating committee considered those to be false statements. The Judicial Conference also cited a separate incident, on which it did not elaborate, saying Fuller in 2010 made a false statement to the chief judge that caused a disruption in operations and a loss of public confidence in the court.

The House committee is not releasing the full report, which contains some sensitive victim information. Fuller was placed on leave after his arrest. In May, he announced that he was resigning effective Aug. 1. The Judicial Council of the U.S. 11th Circuit at the time said Fuller's actions might have warranted impeachment, but the reasons for the determination were not released until this week.

Fuller was appointed to the bench in 2002 by then-President George W. Bush. He is perhaps best known for presiding over the 2006 public corruption trial of former Alabama Gov. Don Siegelman and former HealthSouth CEO Richard Scrushy. 

As celebrity white-collar attorneys surely recall, in recent times a number of prominent public figures ranging from Barry Bonds to Roger Clemens to Marion Jones to 'Lil Kim to Scooter Libby have been federally prosecuted for alleged acts of perjury that seems far less serious and consequential than what the Judicial Conference has found former judge Mark Fuller committed.  Absent some prominent explanation for why a federal perjury prosecution would not be worthwhile in this setting, I will be mighty disappointed and a bit concerned if Fuller does not face sanctions for his apparent criminal behavior in this matter.  (Critically, I am not — at least not yet — asserting that Fuller should be imprisoned for his lying under oath to cover up his misbehavior and stay in his position as a federal judge.  But I am saying (former state DA prosecutor) Fuller ought to at least face federal criminal charges and be subject to the heat that comes with a formal federal prosecution.)
