Two Republican operatives with knowledge of the plans say that North Dakota Gov. Doug Burgum is expected to announce his candidacy for the party’s presidential nomination next month. That puts the governor and former computer software entrepreneur in an already crowded field dominated by ex-President Donald Trump. The Republicans said Burgum plans to launch his campaign June 7 and spoke on the condition of anonymity because the event had not been publicized yet. Burgum has signed legislation rolling back transgender rights, and North Dakota has one of the nation’s strictest anti-abortion laws. But he is expected to emphasize his business background, his small-town roots and a large state tax cut this year.
