NEW YORK — President-elect Donald Trump, a political newcomer who touts his corporate skills, turned businessman-in-chief Tuesday, first demanding the government cancel a multibillion-dollar order for new presidential planes and then hailing a Japanese company’s commitment to invest billions in the U.S. “We will defend American jobs. We have to look at it almost like a war,” Trump said in North Carolina, vowing to keep companies from moving overseas during the second stop of his “thank you” tour to salute supporters.
