They have pointed to the Biden administration’s policies on the Keystone XL pipeline and certain oil and gas leases, which have had little impact on prices.WASHINGTON — As gas prices hit a high this week, top Republican lawmakers took to the airwaves and the floors of Congress with misleading claims that pinned the blame on President Biden and his energy policies.Mr. Biden warned that his ban on imports of Russian oil, gas and coal, announced on Tuesday as a response to Russia’s invasion of Ukraine, would cause gas prices to rise further. High costs are expected to last as long as the confrontation does.While Republican lawmakers supported the ban, they asserted that the pain at the pump long preceded the war in Ukraine. Gas price hikes, they said, were the result of Mr. Biden’s cancellation of the Keystone XL pipeline, the temporary halt on new drilling leases on public lands and the surrendering of “energy independence” — all incorrect assertions.Here’s a fact check of their claims.What Was Said“This administration wants to ramp up energy imports from Iran and Venezuela. That is the world’s largest state sponsor of terror and a thuggish South America dictator, respectively. They would rather buy from these people than buy from Texas, Alaska and Pennsylvania.”— Senator Mitch McConnell, Republican of Kentucky and the minority leader, in a speech on Tuesday“Democrats want to blame surging prices on Russia. But the truth is, their out-of-touch policies are why we are here in the first place. Remember what happened on Day 1 with one-party rule? The president canceled the Keystone pipeline, and then he stopped new oil and gas leases on federal lands and waters.”— Representative Kevin McCarthy, Republican of California and the minority leader, in a speech on Tuesday“In the four years of the Trump-Pence administration, we achieved energy independence for the first time in 70 years. We were a net exporter of energy. But from very early on, with killing the Keystone pipeline, taking federal lands off the list for exploration, sidelining leases for oil and natural gas — once again, before Ukraine ever happened, we saw rising gasoline prices.”— Former Vice President Mike Pence in an interview on Fox Business on TuesdayThese claims are misleading. The primary reason for rising gas prices over the past year is the coronavirus pandemic and its disruptions to global supply and demand.“Covid changed the game, not President Biden,” said Patrick De Haan, the head of petroleum analysis for GasBuddy, which tracks gasoline prices. “U.S. oil production fell in the last eight months of President Trump’s tenure. Is that his fault? No.”“The pandemic brought us to our knees,” Mr. De Haan added.In the early months of 2020, when the virus took hold, demand for oil dried up and prices plummeted, with the benchmark price for crude oil in the United States falling to negative $37.63 that April. In response, producers in the United States and around the world began decreasing output.As pandemic restrictions loosened worldwide and economies recovered, demand outpaced supply. That was “mostly attributable” to the decision by OPEC Plus, an alliance of oil-producing countries that controls about half the world’s supply, to limit increases in production, according to the U.S. Energy Information Administration. Domestic production also remains below prepandemic levels, as capital spending declined and investors remained reluctant to provide financing to the oil industry.Russia’s invasion of Ukraine has only compounded the issues.“When you throw a war on top of this, this is possibly the worst escalation you can have of this,” said Abhiram Rajendran, the head of oil market research at Energy Intelligence, an energy information company. “You’re literally pouring gasoline on general inflationary pressure.”These factors are largely out of Mr. Biden’s control, experts agreed, though they said he had not exactly sent positive signals to the oil and gas industry and its investors by vowing to reduce emissions and fossil fuel reliance.Mr. De Haan said the Biden administration was “clearly less friendly” to the industry, which may have indirectly affected investor attitudes. But overall, he said, that stance has played a “very, very small role pushing gas prices up.”President Biden announced a ban on imports of Russian oil in response to the country’s invasion of Ukraine.Tom Brenner for The New York TimesMr. Rajendran said the Biden administration had emphasized climate change issues while paying lip service to energy security.“There has been a pretty stark miscalculation of the amount of supply we would need to keep energy prices at affordable levels,” he said. “It was taken for granted. There was too much focus on the energy transition.”But presidents, Mr. Rajendran said, “have very little impact on short-term supply.”“The key relationship to watch is between companies and investors,” he said.It is true that the Biden administration is in talks with Venezuela and Iran over their oil supplies. But the administration is also urging American companies to ramp up production — to the dismay of climate change activists and contrary to Republican lawmakers’ suggestions that the White House is intent on handcuffing domestic producers.Speaking before the National Petroleum Council in December, Jennifer M. Granholm, the energy secretary, told oil companies to “please take advantage of the leases that you have, hire workers, get your rig count up.”Understand Rising Gas Prices in the U.S.Card 1 of 5A steady rise.
