Manassas, UNITED STATES:  A man plays poker on his computer connected to an internet gaming site from his home in Manassas, VA 02 October, 2006.  US President George W. Bush this week is expected to sign a bill making it harder to place bets on the Internet, a practice which already is illegal in the United States. Bush was expected to act quickly after Congress approved the Unlawful Internet Gambling Enforcement Act, making it illegal for financial institutions and credit card companies to process payments to settle Internet bets. It also created stiff penalties for online wagers. Billions of dollars are wagered online each year and the United States is considered the biggest market.
