John Edwards' daughter, Cate Edwards, is expected to testify Tuesday in the former U.S. senator and presidential candidate's ongoing corruption trial.
Cate Edwards would be the first family member to do so.
The indicted politician's daughter, 30, broke down in tears and had to leave the courtroom earlier this month amid revelations of Edwards' misdeeds.
Her mother, Elizabeth, passed away in December 2010.
The defense began laying out its case Monday, shifting the focus from Edwards' affair with Rielle Hunter to the specifics of campaign finance law.
Judge Catherine Eagles threw out most of the proposed testimony from former Federal Election Commission Chairman Scott Thomas after prosecutors objected, arguing his opinions and past FEC rulings are irrelevant to the case.
Eagles sent the jury home as Thomas previewed his testimony, saying the use of nearly $1 million to cover up Edwards' affair with Hunter wasn't illegal.
Thomas said in his opinion, "This is a clear-cut case that the payments were not campaign contributions," and thus, did not have to be reported as such.
