Alberta Premier Alison Redford questioning Thomas Mulcair's national leadership.

Mulcair has come under fire from multiple politicians in recent weeks, for stating that the oil sands are driving up the Canadian dollar and killing jobs in the manufacturing sector.

Redford said yesterday through social media that the federal NDP leader's comments were divisive and ill-informed.

And that his claims about unregulated development and disregard for the environment, are false.

On Tuesday Mulcair referred to Redford, as well as the premiers of B.C. and Saskatchewan as "messengers" for Prime Minister Stephen Harper.
