Stock futures are heading lower after a warning from White House economists dampened what had been a huge weekend for retailers.
Dow Jones industrial futures fell 48 points to 12,913. The broader S&P futures have given up 5.8 points to 1,399.50. Nasdaq futures are down 6.25 points to 2,628.
Shoppers flooded stores in record numbers over the weekend, according to the National Retail Federation. The organization says a whopping 247 million shoppers visited stores and websites during the Thanksgiving holiday, up 9.2 percent from last year.
On Monday, however, a new report from the National Economic Council and the Council of Economic Advisers said that a sudden increase in taxes for middle-income taxpayers, if the current fiscal impasse is not remedied, could reduce consumer spending next year by nearly $200 billion.
