From CNN Congressional Producer Deirdre Walsh

WASHINGTON (CNN) -- House Minority Leader Nancy Pelosi told House Speaker Dennis Hastert she viewed his decision to appoint an outside investigator to look into the Foley scandal to be a "unilateral decision," a Pelosi spokeswoman told CNN.

Pelosi spokeswoman Jennifer Crider described the conversation between the Illinois Republican and the California Democrat as: "He said, 'I'm calling to notify you,' and Pelosi responded, 'You'll do what you'll do.'"

It was widely reported that Hastert would appoint former FBI Director Louis Freeh to head the investigation during his Thursday afternoon news, but Hastert said he was still looking for "a person of high caliber."

GOP leadership aides said that Pelosi had objected to naming Freeh, but Crider denied that Pelosi had outright rejected Freeh, saying Pelosi "has the highest respect for his law enforcement credentials, but his expertise is not exploited children."

Pelosi also believes the House ethics committee should be allowed to conduct its investigation and that the rules governing the page program due not need reform, Crider said.

"There is a process and rules in place to protect the pages," she said. "It's not that the rules were inadequate. It's that the rules in place weren't followed by the Republican leadership."
