GREENSBORO, N.C. - Former U.S. Sen. and vice-presidential canditate John Edwards was acquitted on Thursday on one count of taking illegal campaign contributions and the judge declared a mistrial on five other counts because the jury was deadlocked.

The jury's decision came on the ninth day of deliberations, and marked yet another dramatic turn of events for the one-time politician, who rose to become the Democratic Party's vice presidential nominee in 2004 only to see his career ruined by scandal four years later.

As the jury's verdict was read, Edwards, who did not testify in the nearly six-week-long trial, slumped back in his seat in relief.

Later, standing in front of the federal courthouse in Greensboro in North Carolina, the state he represented in the U.S. Senate from 1999 to 2005, Edwards said he never broke the law.

"While I do not believe I did anything illegal, or ever thought I was doing anything illegal, I did an awful, awful lot that was wrong and there is no one else responsible for my sins," he said.

"I am responsible, and if I want to find the person who should be held accountable for my sins, honestly I don't have to go any further than the mirror. It's me. It is me and me alone."

Federal prosecutors did not make clear whether they would seek another trial for Edwards, who they accuse of taking funds from two wealthy donors during his 2008 presidential campaign to keep voters from learning he was cheating on his cancer-stricken wife, Elizabeth, who died in 2010.

Jurors found Edwards not guilty of accepting illegal campaign contributions from one of those supports, Rachel "Bunny" Mellon, in 2008.

But they were deadlocked on a similar count of receiving illegal campaign money from Mellon in 2007; two counts of accepting illegal campaign money from friend and supporter Fred Baron; one count of conspiring to solicit illegal campaign funds; and one count of failing to report the donor payments as campaign contributions.

The defense said all along that the supporters' money was meant as a personal gift to shield Elizabeth Edwards from her husband's indiscretions, not to influence the election.

Asked on Thursday how he felt following the acquittal and mistrial, Wallace Edwards, the former senator's father, pointed at the smile on his face. "This says it all," he said.

Earlier in the day, the jury announced it had reached a decision on a single charge, Count 3, but did not reveal the verdict. It said it could not reach a unanimous decision on the other counts.

U.S. District Judge Catherine Eagles sent the jury back for more deliberations. The jurors came soon came back and said they were deadlocked, prompting Eagles to declare the mistrial on five counts.

The panel was considering whether Edwards, 58, violated election laws as he sought to cover up his affair with videographer Rielle Hunter and her pregnancy with his child during the 2008 campaign for the Democratic presidential nomination. The child, Quinn, is now 4 and lives with Hunter.

The two-time presidential hopeful who served as the Democrats' 2004 vice presidential nominee, faced possible prison time and fines if found guilty of any of six felony counts.

The charges included conspiring to solicit the money, receiving more than the $2,300 allowed from any one donor, and failing to report the payments as contributions.
