US business leaders sound the alarm on US-Canada border blockade

Three of America's largest business groups are warning the trucker-inspired protests along the US-Canada border are further straining stressed-out supply chains.

In a joint statement Thursday night, the US Chamber of Commerce, Business Roundtable and National Association of Manufacturers urged a swift resolution to the blockages.

"The disruptions we are seeing at the US-Canada border -- at the Detroit-Windsor Ambassador Bridge and at other crossings -- are adding to the significant supply chain strains on manufacturers and other businesses in the United States," the trade groups said.
