Either way, someone is lying. The FBI is either lying about the judge's intent or the president is lying about his familiarity with why the judge was there last Saturday.
"Judge Roll was recommended for the federal bench by John McCain 20 years ago, appointed by President George H.W. Bush, and rose to become Arizona's chief federal judge," Obama told the crowd at the University of Arizona. Roll's "colleagues described him as the hardest-working judge within the Ninth Circuit. He was on his way back from attending mass, as he did every day, when he decided to stop by and say, 'Hi,' to his representative."
In the complaint supporting Loughner's arrest, federal prosecutors argue that Roll wasn't simply seeking to pay a social call on Rep. Gabrielle Giffords (D-Ariz.) when he showed up at the community outreach event where the shooting spree took place Saturday. Prosecutors and the FBI insist that Roll "was engaged in official duties" because he wanted to talk to Giffords and her staffers about problems with a surging caseload in federal courts in Arizona, particularly along the Mexican border.
My guess is that the FBI is trying to bolster their case so that there can be a federal prosecution. Why would a federal judge try to catch a sitting congress woman at a town hall type gathering on a Saturday, to discuss anything related to his judiciary problems?
I say, he would have simply picked up the phone and made an office appointment or a lunch date.
Therefore, Obama gets the pass on this one IMO.
