Justice minister briefed on AFP AWU raids

Justice Minister Michael Keenan's office was advised by federal police just before search warrants were executed at two Australian Workers Union offices on Tuesday.

Mr Keenan told AAP on Thursday his office had briefed him shortly afterwards, as was "usual practice".

"Again, in line with usual practice, my office briefed the prime minister's office as the search warrants were being executed," Mr Keenan said.
