Biden calls for three-month suspension of federal gas tax but faces long odds of getting Congress on board

Washington (CNN)President Joe Biden on Wednesday called on Congress to suspend federal gasoline and diesel taxes until the end of September, framing the move as necessary to provide relief to American consumers but itself not enough to resolve the problem of surging energy prices.

Biden's decision to call for a federal gas tax holiday -- a move once derided as a gimmick by Barack Obama and viewed skeptically by leading economists -- almost certainly won't make it through Congress, especially as it faces blowback from the President's own allies on Capitol Hill. House Speaker Nancy Pelosi stopped short of endorsing the plan in a statement after Biden's remarks.

But he cast the move as a way to give some relief to families as he tries to find solutions to one of his top political problems.

"By suspending the 18-cent gas tax, federal gas tax for the next 90 days, we can bring down the price of gas and give families just a little bit of relief," Biden said in a speech from the White House.

"I fully understand that a gas tax holiday alone is not going to fix the problem," he continued, "but it will provide families some immediate relief, just a little bit of breathing room as we continue working to bring down prices for the long haul."

Biden also called on states to take steps removing their own taxes on gas and diesel. And he told oil refining companies to increase their capacity ahead of their planned meeting this week with administration officials.

Combined, Biden claimed, the wish list could reduce the price per gallon of gas by $1. Yet that figure relies on a number of steps entirely out of the President's control -- not least of which is convincing a skeptical Congress to approve his plan.

In her statement after Biden's remarks, Pelosi did not commit to bringing a gas tax holiday up for a vote.

"We will see where the consensus lies on a path forward for the President's proposal in the House and the Senate," she wrote.

The steps amounted to Biden's latest attempt to show he's taking initiative in reducing fuel prices as Americans grow more frustrated by the financial burden. White House officials had been considering a gas tax holiday for months, but held off until now in part because of concerns at how it might be received in Congress.

Republicans widely oppose lifting the gax tax. Even some Democrats -- including President Barack Obama on the campaign trail in 2008 -- have cast a gas tax holiday as a "gimmick."

Yet facing growing anger and the start of the summer driving season, Biden determined that even small steps bordering on symbolic are worth taking.

"In the conditions that we are in today, that's not a gimmick, that's a little bit of breathing room for the American people as we get into the summer driving season," said Amos Hochstein, senior adviser for energy security at the State Department, in an interview on CNN's "New Day" Wednesday morning.

The current federal tax on gas is about 18 cents per gallon, while the federal tax on diesel stands at 24 cents per gallon. Even if savings from lifting those taxes were passed directly to consumers -- which isn't guaranteed -- the savings for one fill-up could only be a few dollars.
