Rep. Jason Chaffetz (R-Utah), chairman of the House Oversight and Government Reform Committee, revealed to reporters Friday that Cheryl Mills, Hillary Clinton’s former chief of staff and current attorney, was granted immunity by the FBI.

According to Chaffetz, Mills relinquished her laptop to federal investigators on the condition that she couldn’t be prosecuted for anything the FBI uncovered during its investigation.

Chaffetz also told reporters that two others — John Bentel, former director of the Office of Information Resources Management at the State Department, and Heather Samuelson, a former Clinton aide — received similar immunity deals.

“No wonder they couldn’t prosecute a case. They were handing out immunity deals like candy,” Chaffetz said. The revelation raises serious questions about the manner in which the FBI investigation was conducted.

The campaign of GOP nominee Donald Trump was quick to pounce on the news.

“Revelations that three additional individuals, including Cheryl Mills, were granted immunity from prosecution in Hillary Clinton’s email scandal shows this was without a doubt a criminal scheme,” Trump senior communications advisor Jason Miller said in a statement.

“At its heart, Clinton’s secret server was an end run around government transparency laws designed to hide corruption between the Clinton Foundation and her State Department, an arrangement which ultimately put our national security and sensitive diplomatic efforts at risk,” the statement from Miller continued.
