U.S. President Joe Biden said the $550 billion infrastructure bill he signed will help propel sales of American-made electric vehicles like the battery-powered Hummers manufactured at the General Motors Co. plant in Detroit he visited on Wednesday.

Biden said the legislation, along with his Build Back Better proposal, would kick-start sales of vehicle batteries, parts and other materials. "We’re going to make sure the jobs of the future end up here in Michigan, not halfway around the world,” Biden said at the plant.

The bill includes not just $7.5 billion to build about 400,000 new electric charging stations, but billions more for roads, rail, and ports. The stakes are immense: White House officials are counting on the legislation to turn around perceptions that both the nation’s economic standing and Biden’s presidency are faltering.
