Shifting positions: Trump administration officials continued to reverse or revise the government’s stance on multiple fronts, including active Supreme Court cases, Jan. 6 prosecutions, school book bans, foreign aid programs and gender definitions. Mr. Trump also reinstated a Republican anti-abortion policy known as the “Mexico City Rule.”

In the first official trip of his second term, Trump also threatened to withhold disaster aid to California unless the state enacts a voter ID law.
