CALGARY, Alberta (Reuters) - A senior aide to U.S. President Donald Trump has scrapped plans to visit Canada for talks with officials in Prime Minister Justin Trudeau’s team, a Canadian government source said on Monday. The source said the planned visit by Trump son-in-law Jared Kushner had hit logistical problems. A separate source had earlier said Kushner intended to meet Trudeau aides on the margins of a cabinet retreat in Calgary.
