OTTAWA – RCMP Commissioner Mike Duheme is concerned that some of the documents on the so-called “green slush fund” sent to Mounties via a controversial House of Commons order are beyond the normal reach of investigators, putting the force in an awkward legal “grey zone.”

In a wide-ranging interview with National Post, Duheme spoke publicly for the first time on the ongoing logjam in the House of Commons over government documents that MPs ordered to be turned over to the RCMP.
