The US oil industry and Republicans are demanding Kamala Harris clarify her energy and climate policy, as the Democratic candidate tries to please her progressive base without alienating voters in shale areas like Pennsylvania, a crucial swing state.
On Thursday, the vice-president said she no longer supported a ban on fracking, the technology that unleashed the shale revolution. But Harris's reversal has not quelled attacks from Donald Trump or US executives that she would damage the country's oil and gas sector.
The heads of the US’s two biggest oil lobby groups said the Democratic candidate must also say whether she would keep or end a pause on federal approvals for new liquefied natural gas plants, and whether she supported curbs on drilling imposed by the Biden administration.
