GREENSBORO, N.C. -- The jury deciding the fate of John Edwards in North Carolina has finished a second day of deliberations without reaching a verdict.

The former presidential candidate faces 30 years in prison after pleading not guilty to six campaign finance corruption charges. The jury began considering its decision Friday, after nearly four weeks of testimony. On Monday, the jurors asked to see eight evidence exhibits but did not reach a verdict.

Prosecutors have accused the Democrat of masterminding a scheme to use nearly $1 million in secret payments from two donors to help hide his pregnant mistress as he sought the White House in 2008.

Defense attorneys argued Edwards had little direct knowledge of the cover up, which they say was directed by his campaign finance chairman and a trusted aide who falsely claimed paternity of his boss' baby.
