Loughner Pleads Not Guilty
Accused Tucson gunman's defense likely to hinge on sanity argument.
Accused Tucson gunman Jared Loughner has pleaded "not guilty" in the first charges brought against him in the wake of the attack on Congresswoman Gabrielle Giffords that left six dead and more than a dozen others, including Giffords, wounded.
The plea likely lays the ground work for his defense team to ultimately pursue a not-guilty-by-reason-of-insanity plea.
Even if unsuccessful, focusing on Loughner's history of mental issues could provide defense attorney Judy Clarke with the opportunity to argue he should not face the death penalty.
As the legal battle slowly unfolds in Arizona, there has also been a delay in Texas.
Doctors at Memorial Hermann Hospital in Houston will keep Gabrielle Giffords in intensive care a bit longer than planned because of a build-up of fluid on her brain.
