U.S. stock futures mixed after Greece rescue deal

U.S. stock futures are nearly flat as traders await a resolution to the impasse over the U.S. debt limit. News of a second bailout for Greece is lifting overseas markets.

Republicans and Democrats are far apart on a deal to raise the nation's debt ceiling before Aug. 2, when the U.S. might default on its financial obligations. That uncertainty has overshadowed positive news about corporate earnings and an agreement Thursday to give Greece a second financial lifeline.

European officials also agreed to lower interest rates for loans to Greece, Ireland and Portugal.

Ahead of the opening bell, S&P 500 futures are up 1 point, or 0.1 percent, at 1,343. Dow futures are down 8, or 0.1 percent, at 12,682. Nasdaq 100 futures are down 3, or 0.1 percent, at 2,408.
