Biden to urge Congress to suspend gas tax for three months

Prices could drop by about $1 a gallon at the pumps if measures are adopted but experts question effectiveness of gas tax holidays

Joe Biden will call on Congress today to temporarily suspend federal gasoline and diesel taxes in an attempt to quell voter anger at the surging cost of fuel.

In a speech on Wednesday afternoon, Biden is expected to ask the House to pause the federal taxes - about 18 a gallon for gas and 24 a gallon for diesel - until the end of September.
