By\u00a0Patrick Svitek\r\nFour Texas Democrats in Congress are warning President Joe Biden against restricting U.S. oil exports as a way of fighting high gas prices.\r\n\u201cWe urge you and your administration to reject any well-intentioned but misguided calls to curtail American crude oil and\/or petroleum exports in reaction to the high gasoline and diesel prices currently seen at the pump,\u201d the Texas Democrats say in a new letter to Biden. \u201cAs you know, domestic gasoline prices are set by an international benchmark (Brent), and restricting US crude exports would lower global supply and increase costs here at home.\u201d\r\nThe letter was led by two South Texas Democrats, Reps.\u00a0Henry Cuellar\u00a0of Laredo and\u00a0Vicente Gonzalez\u00a0of McAllen, and the other Texas Democrats who signed were Reps.\u00a0Sylvia Garcia\u00a0and\u00a0Lizzie Pannill Fletcher of Houston. Other signatures come from California Democratic Rep. Lou Correa and Rep. Tim Ryan, D-Ohio.\r\nIt is the latest example of how Cuellar and Gonzalez are on edge over Biden\u2019s approach to the oil and gas industry as Americans deal with high prices at the pump. The average U.S. gas price has hovered around $5 per gallon\u00a0in recent days.\r\nLast week, Cuellar and Gonzalez separately pushed back on a letter Biden wrote to major U.S. oil refiners, telling them to increase supply and that \u201chistorically high\u201d profit margins are unacceptable. Gonzalez urged Biden to \u201cstop with the blame game,\u201d while Cuellar said the letter \u201cdoes not resolve the issue at hand.\u201d\r\nNow the lawmakers appear concerned the Biden administration may try to issue new restrictions on U.S. oil exports. Bloomberg\u00a0reported Thursday\u00a0that top Biden administration officials were mulling restricting such exports and that discussions \u201chave picked up in recent days.\u201d\r\nThe lawmakers argue that curtailing U.S. oil exports would lead to costly inefficiencies because \u201crefineries would no longer have the flexibility needed to optimize output.\u201d\r\n\u201cThis would be a misguided policy now, and it would be a misguided policy in the future,\u201d the lawmakers say.\r\nBoth Cuellar and Gonzalez are running for reelection as national Republicans try to gain new ground in South Texas. Republicans\u00a0got a boost\u00a0by flipping an open seat there in a special election last week, and the GOP winner, Mayra Flores, will face Gonzalez in November.\r\nThis story was originally published by the Texas Tribune.
