(CNN) — It is unlikely that John Edwards’ former mistress will testify for his defense, or at all during his corruption trial, a source close to the case told CNN.
With Edwards’ defense team coming close to wrapping up its case, the ex-mistress, Rielle Hunter, remained on the defense witness list.
But the source said it is “unlikely” that she will testify at all in the trial. Last week, prosecutors did not to call Hunter to the stand before they rested their case.
The defense may still call Edwards’ eldest daughter, Cate, to testify Wednesday, and may recall prosecution star witness Andrew Young, a former Edwards campaign aide.
The former U.S. senator’s trial is under way in Greensboro, North Carolina. He is charged with six counts of illegal campaign contributions, conspiracy and falsifying documents. The trial is in its fourth week and halfway done. If found guilty on all charges, Edwards faces up to 30 years in prison and a $1.5 million fine.
The government alleges Edwards “knowingly and willingly” accepted large amounts of money from wealthy campaign donors to hide Hunter and her pregnancy in an effort to remain a viable candidate in his 2008 presidential campaign.
Hunter lives a distance from Edwards in North Carolina. However, they both parent their 4-year-old daughter.
A friend and adviser to Edwards testified Tuesday that the candidate appeared surprised to learn that an elderly heiress sent money that ended up going to Hunter and Young.
The defense, which began its case Monday, has argued that Young largely used the money for his own personal gain, while also paying for Hunter’s medical expenses during her pregnancy in an effort to hide the affair from Edwards’ wife. Donations for that purpose, the Edwards team has argued, cannot be considered in violation of campaign finance laws.
