Prosecutors seeking to try John Edwards for campaign finance violations have filed a stack of motions rebutting the former presidential candidate's contention that the case against him is fundamentally flawed.

Lawyers for Edwards filed five motions earlier this month asking a federal judge to dismiss all six felony and misdemeanor counts, arguing that case is the work of a partisan prosecutor.

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.

In motions filed late Monday, prosecutors reiterated their position that the secret payments to support the mistress were not gifts, but contributions intended to preserve the viability of his campaign.

Trial is to begin in January.
