The leader of the federal Conservatives says he is launching an independent, third-party investigation into how a former M-P accused of sexual assault was allowed to run for election.
Andrew Scheer says the party can't determine the facts about how Rick Dykstra was allowed to run in 2015 while sources are still talking to the media.
Dykstra stepped down as president of the Ontario Progressive Conservatives amid allegations of sexual assault dating back to his time on Parliament Hill.
The accusations were known to the federal party.
