Wall Street posted its worst trading day yet of 2017, after President Donald Trump's immigration policies appeared to worry investors. 

The Dow fell 122 points to close at 19,971. 

The S&P lost 13 points to 2,280 and the Nasdaq deceased 47 points to 5,613. 

Trump signed executive action last week to deport undocumented immigrants involved in criminal activity, and another that effectively denies entry to refugees from seven "terror-prone" Muslim-majority countries.
