Senior One Nation figures have been secretly recorded asking for millions of dollars in political donations from the NRA and Koch Industries by Al Jazeera Journalists.

Pauline Hanson’s chief of staff James Ashby and One Nation’s Queensland leader Steve Dickson were involved in several meetings with pro-gun lobbyists last September during a trip to Washington.

The meetings were covertly recorded by a journalist posing as a gun lobbyist and included conversations about seeking political funding and how to spin gun massacres against gun control advocates.

The two-part investigation will air tonight on ABC.
