FLASHBACK: Biden, Buttigieg and Harris supported banning sale of gas and diesel vehicles in U.S.

President Joe Biden, Vice President Kamala Harris and Transportation Secretary Pete Buttigieg supported a federal ban on the sale of gas and diesel vehicles in the U.S. when competing for the 2020 Democratic presidential nomination.

New York state announced a ban on the sale of most gas and diesel vehicles by 2035. California Gov. Gavin Newson previously announced a similar state government ban.

As a candidate in the 2020 Democratic presidential primary, Buttigieg supported a federal ban on the sale of gas and diesel vehicles in the U.S. by 2035.

Harris proposed requiring every vehicle sold in the U.S. to be "zero-emissions" vehicles by 2035. Biden had a similar plan that would take effect by an unspecified date.
