Tomorrow MPs will vote whether or not to call Katie Telford, Chief of Staff to the Prime Minister, to testify at the parliamentary committee investigating allegations of electoral interference by the People's Republic of China.

I ask my colleagues from the NDP to stand up to their Liberal coalition partners, do the courageous thing, and support our motion.

Canadians deserve to have their questions answered, and their faith in our elections restored.
