GREENVILLE, PITT COUNTY -

Former U.S. senator and Democratic presidential hopeful John Edwards was back in the Pitt County Courthouse Thursday to help represent a 4-year-old Virginia boy in a medical malpractice case.

Edwards is one of three attorneys representing the parents and guardians of a boy with brain damage and physical injuries they say occurred in December 2009. At that time, the boy was an infant in the care of Pitt County Memorial Hospital and an emergency room doctor.

The attorneys say hospital staff failed to make sure the child received adequate oxygen.

In court Thursday, the first witness took the stand and went over the records from the transport of the patient.

Attorneys say cross examination may be delayed until next Wednesday due to scheduling issues.

In 2012, Edwards faced six felony charges in a case involving nearly $1 million provided by two wealthy political donors to help hide his pregnant mistress Rielle Hunter as he sought the White House in 2008.

A jury acquitted Edwards on one count of accepting illegal campaign contributions and deadlocked on the remaining five.
