Government Executive: Only weeks ago, Nikki Haley seemed in lockstep with Donald Trump as she accompanied the president around the United Nations General Assembly in New York and reinforced his “America First” message at every turn. “We have pulled out of the Paris Accord [on climate change]. We have pulled out of the Global Compact [for Migration]. We have pulled out of the Iran deal,” the U.S. ambassador to the UN boasted to reporters, in explaining how her boss was safeguarding America’s sovereignty. Just ahead of the General Assembly, I’d watched her proudly declare during a conference in Washington, D.C., that it was “a new day in our country,” in which the United States would no longer provide foreign aid to hostile countries.
