US President Donald Trump and his inner circle are using unrest in France to push unsubstantiated claims blaming the riots on immigration, even showing French protest footage at midterm rallies.

Trump's focus comes as Republicans face mounting pressure ahead of the midterms and his approval rating hits a reported record low.
