Pete Hoekstra, controversial US ambassador to Canada, has also accused Canadian officials of interfering in US elections

The US ambassador has suggested Canada could be blamed if Republicans perform poorly in next week’s midterm elections, the latest intervention from a controversial figure who has been accused of inflaming a bitter dispute that has angered and baffled residents of both countries.

On Wednesday, CTV news reported that Pete Hoekstra told business leaders at a closed door meeting that if a number of swing races – including Maine and Michigan – go to the Democrats, it could make things harder for Canada because Donald Trump might try to blame the loss on it.
