Major U.S. stock-indexes little changed on Thursday, as investors turned wary following President Donald Trump's latest protectionist comments. Trump in a meeting with key lawmakers said he would like to speed up talks to either renegotiate or replace the North American Free Trade Agreement (NAFTA). Investors are also assessing possible consequences of Trump's other comments, including labeling a refugee swap agreement with staunch ally Australia as a "dumb deal" and putting Iran "on notice" for firing a ballistic missile.
