Trump drops some Canada tariffs in bid to boost embattled Susan Collins in Maine

Republican senator faces critical re-election battle in state where president's trade war has outraged voters

Donald Trump dropped some of the US's tariffs on Canada on Friday to better serve the public interest" the White House said, handing a win to Susan Collins, the embattled Republican senator for Maine, as she faces a tight re-election campaign that will help determine whether Democrats can flip control of Congress.

Collins announced that the exemptions would apply to nine agricultural products, including blueberries, potatoes, apples and seaweed. She added that many of the state's farmers rely on specialized equipment and materials from across the border that are unavailable from American suppliers or cannot be replaced without incurring significant expense".
