Former aide Andrew Young, the star witness in the trial of former presidential candidate John Edwards, began his testimony against his former boss Monday.
Edwards is accused of using hundreds of thousands of dollars from 101-year-old Rachel "Bunny" Mellon and Fred Baron to conceal his affair with Rielle Hunter.
Young, testifying as the first witness Monday, said Mellon was an enthusiastic supporter who apologized for not being able to give more than $1 million.
"She said she was close personal friends with Senators John and Bobby Kennedy and felt like Edwards was the best combination of them," Young testified.
Prosecutors say Edwards broke federal law by accepting about $725,000 from Mellon and more than $200,000 from Fred Baron, a now-deceased Texas lawyer.
The money was used to pay for Rielle Hunter's living and medical expenses, travel and accommodations to quash the scandal while he sought the presidency.
Edwards is accused of concealing the money from the public and the Federal Election Commission, which polices political contributions, in the 2008 campaign.
