ORIGINAL STORY: President Trump has identified a new enemy on Twitter: Canada.
On the heels of confirming that he would hit Canada with new tariffs on imported lumber, Trump accused Canada of making life for dairy farmers in Wisconsin "very difficult."
Trump is set to sign an executive order Tuesday that will create a task force to find things keeping American farming businesses from growing, CNN reports.
Canada has made business for our dairy farmers in Wisconsin and other border states very difficult. We will not stand for this. Watch!— Donald J. Trump (@realDonaldTrump) April 25, 2017
Trump insisted, "We will not stand for this."
The task force created by the order will require a report to be sent to the president in 180 days.
Trump also accused Canada of cutting off dairy products being exported from the United States. He may be targeting lumber because U.S. lumber companies allege Canadian lumber imports are unfairly subsidized, which Canada denies, The Hill reports.
Canadian Prime Minister Justin Trudeau fired back on Tuesday, saying, "Standing up for Canada's interests is what my job is, whether it's soft wood or software" as the Canadian dollar hit a 14-month low.
