The President will request a 3-month federal gas tax holiday.
The decision "before the end of the week" was mentioned by Biden two days ago.
But in April 2008, Obama stated, "We don't know that the oil corporations will truly pass on the savings."
According to AAA, the average price of a gallon of gas today is $4.97.
Average gas prices in California are $6.38 per gallon, more than $5.50 in Washington, Oregon, and Nevada.
Americans might save up to $1 or more per gallon on gas if oil firms and retailers also cooperate.
A nationwide gas tax holiday, according to Biden, could save Americans up to 18.4 cents per gallon.
The President will request this from Congress and ask the states to halt their gas taxes.
According to some economists, that won't result in significant fuel-price reductions and would undermine efforts to control inflation.
If it was started in March and continued through the end of the year, the savings per person might only be about $50.
