U.S. stock index futures pointed to a slightly lower open on Thursday as traders eyed the release of data and a key vote in the House.
The House is set to vote on the Republican health care bill that, if signed into law, would repeal and replace Obamacare. Investors have been keeping a close eye on the vote as a prolonged battle on the health-care front could delay market friendly measures, including tax reform and fiscal stimulus.
Expectations for such policies had been a boon for the market's postelection rally.
On the data front, initial jobless claims rose 15,000 to 258,000, above the expected 240,000. New home sales are set to come out at 10:00 a.m. ET.
