WASHINGTON (CNN) -- Former CIA agent Valerie Plame Wilson testified Friday that it was not her idea for her husband, former ambassador Joe Wilson, to make a trip to Niger to investigate an allegation that Iraq had sought yellowcake uranium.

"I did not suggest him. I did not recommend him. There was no nepotism involved," she said, adding, "I did not have the authority."

It was the suggestion of another CIA officer who knew that Joe Wilson had previously gone on other CIA missions "to deal with some other nuclear matters," she said.

Later, she was asked to write an e-mail summarizing the discussion that included the possibility of her husband going. A portion of that e-mail was later taken out of context to make it seem that she had suggested her husband go, she said.

Joe Wilson found the allegations about Iraq's attempted purchase were unsubstantiated. When the Bush administration cited the allegation as an argumentfor war, Wilson publicly contradicted the administration. He accused the Bush administration of purposely leaking his wife's identity in response. ( Watch Video: Plame describes being outed)
