The Financial Post reports in its Tuesday, Aug. 4, edition that 25 U.S. states, nearly all led by Democrats, sued the Trump administration on Monday over wide-ranging tariffs, arguing that President Donald Trump had exceeded his authority in imposing the new levies on dozens of countries, including Canada. An Agence-France Presse dispatch to the Post reports that the coalition of states argued in a court filing, "There is no rational fit between the purported problem of forced labour in international supply chains and the blanket global tariffs the USTR imposed." The challenge is related to Mr. Trump's latest salvo of tariffs of between 10 and 12.5 per cent imposed against 60 trading partners -- forming the bulk of United States imports -- last month. Canada will face a tariff of 10 per cent, but most goods will escape it because they will be exempt under the U.S-Mexico-Canada Agreement. The tariffs were imposed after probes by the USTR's office over allegations of "forced labour," conducted under Section 301 of the Trade Act of 1974. Since taking office for his second term, Mr. Trump has upended global trade by imposing wide-ranging tariffs against friends and foes alike.
