RALEIGH, N.C. (AP) — Attorneys for ex-presidential hopeful John Edwards have lashed out at the criminal case against the former North Carolina senator by expanding their argument that the charges against him should be dismissed.In a flurry of court filings on Tuesday, Edwards' lawyers aimed to rebut arguments made last month by prosecutors who want the case to go forward against the 2004 Democratic vice presidential nominee.A trial in the case is scheduled for January, but Edwards' defense team hopes a judge will throw it out of court.Edwards is charged with using funds from campaign contributors to cover up his affair with Rielle Hunter, a videographer who became pregnant with his child.His lawyers say the prosecution was politically motivated and that Edwards had committed no crime.
