US President Donald Trump’s topline energy policy objectives are front and center in the massive Republican-only legislation that cleared the US House of Representatives by a razor-thin margin last month. The energy and tax megabill is the Republican party’s best shot at cementing durable wins for Trump’s energy agenda, including permanently clawing back more than $570 billion in clean energy spending and codifying long-sought oil and gas permitting victories. But the bill could still undergo significant changes in the Senate, especially to energy provisions, which in turn threatens its passage in the House, and the tight self-imposed July 4 target for putting a bill on Trump’s desk does not help.
