July 27 (Reuters) - U.S. House Speaker Nancy Pelosi's husband sold his shares of chipmaker Nvidia (NVDA.O) on Tuesday, days before the House is expected to consider legislation providing subsidies and tax credits worth over $70 billion to boost the U.S. semiconductor industry.

In a periodic transaction report, the senior Democrat disclosed that her husband, financier Paul Pelosi, sold 25,000 shares of Nvidia for about $4.1 million, ending up with a loss of $341,365.
