GM has come under harsh criticism from lawmakers from both major political parties, and from President Donald Trump, since Monday when it announced the biggest restructuring for the U.S. No. 1 carmaker since its bankruptcy a decade ago.
Barra is expected to meet with lawmakers from Michigan and Ohio, where GM plans to shutter three plants, as well as senior leaders in Congress. GM did not immediately comment.
Barra has been calling lawmakers this week to explain the decision to end production. Trump has threatened to revoke subsidies for GM.
The Detroit automaker plans to halt production next year at three assembly plants: the Lordstown small-car factory near Youngstown, Ohio; the Detroit-Hamtramck complex in Detroit; and the Oshawa, Ontario, assembly complex near Toronto. It will also stop building several models now assembled at those plants, including the Chevrolet Cruze, the Chevrolet Volt hybrid, the Cadillac CT6 and the Buick LaCrosse.
Additionally, GM plans to shutter the Warren transmission plant outside Detroit and a plant that makes electric motors and drivetrains outside Baltimore, Maryland.
The Cruze compact car will be discontinued in the U.S. market in 2019, although GM may continue building it in Mexico for other markets, Barra said.
