Scott Walker has been taking a tremendous amount of heat over a secret email list that was used in his office when he was serving as the Milwaukee County Executive.

A cache of nearly 30,000 emails shows the extent to which aides campaigned for Scott Walker on the taxpayers' dime.

Included in more than 27,000 pages of emails and other documents unsealed Wednesday are the closest links yet between Gov. Scott Walker and a secret email system used in his office when he was Milwaukee County executive.

"Consider yourself now in the 'inner circle,'" Walker's administration director, Cynthia Archer, wrote to Walker aide Kelly Rindfleisch just after the two exchanged a test message.

"I use this private account quite a bit to communicate with SKW and Nardelli. You should be sure you check it throughout the day," she wrote, referring to Walker by his initials and to Walker's then-chief of staff, Tom Nardelli.

Today Walker appeared on Fox News Sunday and when asked about the email dump and whether he knew about the secret list, he shucked and jived his way out of responding to the questions

Wisconsin Gov. Scott Walker (R), who has been under scrutiny after thousands of emails were released to the public last week, on Sunday would not address the documents and instead blamed the recent focus on the emails on Democratic operatives.

"We have our political operatives at the DNC and the DGA that desperately want to switch the subject from the fact of things like us taking a $3.6 billion budget deficit and turning it into a nearly billion dollar surplus," he said on "Fox News Sunday." "They don't want to talk about the improvement in the economy. They don't want to talk about the successes we've had in our state. Instead they desperately want to switch the subject -- a subject that's already been resolved."

When host Chris Wallace asked why Walker's staff had been using private email accounts if they had done nothing wrong, the governor refused to address the issue."You're not answering my question," Wallace told the Walker.

His response was to instead focus on the attention he's getting on Democratic operatives. But there are still questions to be asked:

Mike Tate, chair of the Democratic Party of Wisconsin, said there are additional questions that Walker needs to answer.

"What we continue to see is the further erosion of public trust in the governor's judgment," Tate said. "Did he know his staff was breaking the law, and if he didn't, how is that possible with what has come to light? How will his public and campaign staffs interact moving forward? And how do citizens know that their tax dollars won't be misused by mixing private-public staff going into an election year?"
