Oil prices fell around 1% on Tuesday, as U.S. lawmakers prepared to wrangle over an economic stimulus package and investors worried about a rise in coronavirus cases worldwide.
Brent crude futures fell 19 cents, or 0.44%, to $43.22 a barrel, while West Texas Intermediate crude futures settled 56 cents, or 1.35%, lower at $41.04 per barrel.
U.S. Republicans unveiled a new coronavirus relief proposal on Monday, four days before millions of Americans lose expanded unemployment benefits. On Tuesday, they faced difficult talks with Democrats on how best to recover from the coronavirus pandemic.

Also a negative for prices, U.S. consumer confidence ebbed in July amid a flare-up in COVID-19 infections across the country. Cases worldwide have risen to around 16.57 million people.

"This suggests that the tightening we were seeing in the market has eased somewhat, with the demand outlook more uncertain given the resurgence of COVID-19 cases in some regions," said Warren Patterson, ING's head of commodities strategy.
Industry data on U.S. stockpiles is due later on Tuesday. Analysts polled by Reuters expect U.S. crude oil stockpiles were likely unchanged last week, while inventories of refined products probably declined.
