Stock futures mixed as debt stalemate continues

NEW YORK — U.S. stock futures are mixed as lawmakers remain at odds over how to avoid a debt default.

House Speaker John Boehner had planned to hold a vote on his debt-limit plan on Wednesday. But that was postponed after congressional budget officials said the proposal would cut spending less than advertised. The White House had also threatened to veto Boehner's plan.

The stalemate has put financial markets on edge. If an agreement is not reached by Aug. 2, the U.S. may not have enough cash to pay all its bills.

Ahead of the opening bell, Dow Jones industrial average futures are up 6, or 0.1 percent, at 12,438. Standard & Poor's 500 futures are down 2, or 0.1 percent, at 1,324. Nasdaq 100 futures are down 3, or 0.1 percent, at 2,420.
