President Trump's top economic adviser on Monday said the White House wants to end subsidies for electric vehicle purchases, without saying how it would eliminate the incentives that were created by Congress.

Larry Kudlow, director of the White House National Economic Council, told reporters that electric car subsidies "will all end in the near future," adding 2020 or 2021 when asked for a timeline.

He also said no plans are in place to cut off General Motors Co. from federal spending after President Trump last week directed agencies to explore how to do so after lashing out on Twitter at the automaker's plans to close plants and cut thousands of jobs.
