Vice President Joe Biden’s office stonewalled a Freedom of Information Act (FOIA) request for his travel expenses, according to Ronald Kessler’s new tell-all book on the Secret Service, The First Family Detail.

Kessler, a former Wall Street Journal and Washington Post investigative reporter, filed a FOIA request in April 2013 with the Air Force for the details and costs of Biden’s personal trips.

“But in what amounts to a cover-up on behalf of the vice president, on June 6, Biden’s office blocked transmitting the results to me and told Air Force officers they were not to comment to anyone about the case,” Kessler writes.

According to Kessler, Biden’s then-deputy counsel Jessica Hertz took over the FOIA case from the Air Force and ordered it not to release the 95 pages of documents it had compiled in response to Kessler’s request.

“They are covering up,” an Air Force officer told Kessler. “We spent a lot of time compiling the records, but Biden’s office said logs for each flight would have to be consulted. This is a smokescreen designed to delay providing any records as long as possible.”
