Republicans threaten Canada with sanctions over drifting wildfire smoke

Fires are also blazing across the US and the Trump administration has repealed several climate protections

US Republicans are threatening to sanction Canada and Canadian government officials after smoke from devastating wildfires has drifted across huge swathes of the US, creating hazy conditions and dangerous air quality for tens of millions of Americans.

Donald Trump on Friday blamed his country's northern neighbor for the smoke spreading from wildfires and said he planned to call Mark Carney, the Canadian prime minister, to ask about Ottawa's plans for dealing with the blazes.
