NEW YORK (AP) — Wall Street is drifting in mixed trading after Washington struck a tentative deal to avoid a potentially disastrous default on its debt. The S&P 500 was 0.1% higher in Tuesday midday trading, remaining near its highest level in nine months. The Dow Jones Industrial Average was down slightly, while building excitement about artificial intelligence helped the Nasdaq composite to lead the market with a 0.5% gain. President Joe Biden and House Speaker Kevin McCarthy are working to win votes for a deal reached over the weekend to allow the U.S. government to borrow more money.
