U.S. stock index futures pointed to a lower open on Thursday after President Donald Trump said the dollar was getting "too strong," while earnings season kicked off.

Trump's comments sent the dollar reeling, with the greenback hitting its lowest level of the month against a basket of currencies. The remarks also added jitters to an already nervous market, as investors continue to weigh where the administration's priorities are.
