GREENSBORO, N.C. - The eldest daughter of John Edwards is set to take the stand in the former U.S. presidential contender's defence.

Cate Edwards is a 30-year-old lawyer who has sat behind her father nearly every day of his corruption trial. She's expected to testify Tuesday.

Edwards is accused of masterminding a plan to use nearly $1 million from two donors to help hide his pregnant mistress as he sought the White House in 2008.

He has pleaded not guilty to six counts related to campaign finance violations.

Cate Edwards fled the courtroom during earlier testimony about her mother's reaction to her father's affair with Rielle Hunter.

Edwards faces up to 30 years in prison.
