Federal prosecutors seeking to try John Edwards for campaign finance violations have filed a sealed response to the former presidential candidate's motion asking a judge to dismiss the charges.
Court records indicated Monday that the motion cannot be accessed by the public.
Edwards' defense team filed five motions earlier this month saying the case against him is fundamentally flawed and that prosecutors failed to screen the federal grand jury that issued the indictment for bias.
Edwards is accused of using about $1 million in undisclosed payments from campaign donors to cover up an affair during his 2008 run for the White House. He has pleaded not guilty to six felony and misdemeanor counts.
A trial is set to begin in January.
