Asked about actions planned after General Motors announced U.S. plant closings and layoffs last week, Kudlow pointed to the $2,500-to-$7,500 tax credit for consumers who buy plug-in electric vehicles, including those made by GM, under federal law.
". , . As a matter of our policy, we want to end all of those subsidies," Kudlow said. "And by the way, other subsidies that were imposed during the Obama administration, we are ending, whether it's for renewables and so forth."
Asked about a timeline, he said: "It's just all going to end in the near future. I don't know whether it will end in 2020 or 2021. . . ."
Experts say the White House cannot change the cap unilaterally. U.S. President Donald Trump last week threatened to eliminate subsidies for GM in retaliation for the company's decision.
Kudlow made clear any changes in subsidies would not just affect GM. "I think legally you just can't," he said.
Democrats will take control of the U.S. House in January and are unlikely to agree to end subsidies for electric cars and many have been pushing for additional incentives.
