Speaker of the House Mike Johnson indicated Tuesday that he will try to save some of the green energy subsidies

House Speaker Mike Johnson said President Joe Biden’s signature climate law would be an early target for Republicans if Donald Trump wins the presidency and the party secures control of Congress after the November election.

In an exclusive interview with CNBC, Johnson says he will use "a scalpel and not a sledgehammer" in deciding which IRA tax credits to try to roll back.

Trump would have a hard time repurposing that money thanks to protections in the 1974 Impoundment Control Act, according to Gillian Metzger, a Columbia University law professor. That law was passed after President Richard Nixon impounded funds for federal spending he opposed on policy grounds.

Former President Donald Trump has said he would cancel all unspent funds from President Joe Biden's signature climate law if he wins the presidential election on Nov. 5. But the vast majority of grants will be spent by the time a new president takes office in January,

As President Biden’s signature climate law spurs energy investments in Republican-led districts, many Republican members are getting on board with keeping at least some of its tax credits — including the Speaker of the House.
