* Dow down 8 pts, S&P up 0.5 pts, Nasdaq up 15.5 pts
Aug 18 (Reuters) - U.S. stock index futures were little changed on Friday, a day after the S&P posted its biggest daily percentage loss in about three months, on mounting worries about President Donald Trump's ability to legislate his pro-growth agenda.
* Trump's campaign promises of tax cuts and higher infrastructure spending had helped the market rally, with the S&P climbing 13.6 percent since the Nov. 8 presidential election.
* Trump has alienated Republicans, corporate leaders and U.S. allies, while rattling markets with his comments since Saturday's violence in Charlottesville, Virginia, which came in the aftermath of a white nationalist protest against the removal of a Confederate statue.
Several business leaders have since resigned from his advisory councils and a White House official said plans for an infrastructure council had been dropped..
* Adding to the woes were a speculation of a possible departure of White House Economic Adviser Gary Cohn, which was later denied by the White House.
* Investors flocked to less-risky assets, with gold poised for its second straight weekly gains and U.S. Treasury yields falling after a deadly attack killed at least 13 people in Barcelona on Thursday.
* Earlier in the week, minutes from the Federal Reserve's July meeting showed officials were concerned about recent inflation readings that remain below the Fed's 2 percent target rate, clouding the path of interest rate hikes this year.
* Dallas Fed Chief Robert Kaplan will speak at an event later in the day. Kaplan, a policymaker in the Fed's cautious camp, said on Thursday the Fed should be "very patient and judicious" as it considers whether to raise rates.
* Economic reports on Friday include the University of Michigan's consumer sentiment survey data for August due at 10:00 a.m. ET (1400 GMT).
* Shares of Estee Lauder were up 4.76 percent in premarket trading after the cosmetics maker reported a rise in quarterly profit.
