evidence: There are many factors at play in the steady climb in gas prices since Biden took office, including increased demand after pandemic lockdowns ended, inflation and, now, the war in Ukraine. But lower oil production in the U.S. isn’t one of them. [...] A month into Biden’s presidency, PolitiFact began seeing claims that blamed Biden’s policies for increases in gas prices. But energy experts we spoke to said it was largely due to supply and demand rather than presidential policies. The coronavirus pandemic prompted a big fall in oil demand and gasoline prices, due to declines in driving and air travel. As the economy has slowly rebounded, growing demand has boosted prices at the pump. [...] A Facebook post claims that Biden "shut down production" in the U.S., which is why gas prices are so high. The post also falsely claims Biden was "installed" in November, with a graphic showing that the rise in gas prices began under his watch. This is misleading, as Biden was inaugurated on Jan. 20, 2021.
