Earlier today, another member of Edwards' communications team, Wendy Button also testified.
Button volunteered to help Edwards write a statement finally accepting paternity of Frances Quinn and the two spoke often and rewrote the statement a dozen times over two months in the summer of 2009.
Strangely Edwards insisted that the statement be vetted not only by his lawyers but Hollywood actors including Sean Penn and Madeleine Stowe, star of the ABC soap opera "Revenge."
Button testified that John Edwards told her that he knew all along that Baron was taking care of Hunter, but removed a line from the statement that acknowledged such. The statement they worked on was never issued. Edwards finally acknowledged paternity in January 2010.
Hunter had been on the list of potential witnesses the prosecution might call. Though the government will pass on putting Hunter on the stand, Edwards' defense team may still do so.
"There is one person who seems to be at the center of all of this, these spinning planets, and that's Rielle Hunter," Steve Friedland, professor of law at Elon University, told ABC News.
Edwards claims the money was used to hide the girlfriend from his wife, not the government.
If convicted, Edwards could be sentenced to 30 years in prison.
