After crude oil slipped below $80 a barrel last week, it's back up this week, propped up by boosts in the U.S. stock market and a weaker dollar, according to reports by Dow Jones. Crude closed trading Monday at $81.25 a barrel on the New York Mercantile Exchange, Dow Jones reports. The news service attributes the stock market gains to the passage of the health care reform bill in the U.S. House of Representatives Sunday night.
