An ex-speechwriter for John Edwards will take the witness stand at the former presidential candidate's corruption trial.
Wendy Button is expected to testify Edwards asked her in the summer of 2009 to help draft a public statement admitting he had an affair and fathered a baby outside his marriage. Edwards reportedly told Button he knew about the nearly $1 million provided by wealthy donors that helped hide his pregnant mistress as he sought the Democratic nomination in 2008, but there were legal reasons he couldn't disclose his knowledge of the cover up.
Edwards now denies knowing about the money and has pleaded not guilty to six criminal counts related to campaign finance violations. He faces up to 30 years in prison and $1.5 million in fines if convicted.
