She also said that she is working to place the Lordstown workers at other GM facilities where possible.
"A strong GM is the best way for me to maintain the 90,000-plus jobs we have across the USA, in addition to all the people who have retired from GM and their pensions", she said.
GM had conversations with the union previous year about making concessions that would give the plant a better chance to stay open, said two people familiar with the matter. We want to keep that product here. She also noted GM is launching a number of new vehicles in MI next year.
"I share their concerns about the impact the actions we announced last week will have on our employees, their families, and the communities", Mary Barra said in a statement.
Mary Barra emerged from the Washington meeting Thursday, saying it was "very productive".
GM is ending production at its Detroit-Hamtramck Assembly plant next year, as well as at its Warren Transmission plant in suburban Detroit, along with plants in Ohio, Maryland and Canada and eliminating about 8,000 salaried positions.
Barra met on Wednesday with Ohio's Congressional delegation about the planned closure of the sprawling Lordstown Assembly plant, which makes the Chevrolet Cruze.
Portman said he and Brown urged Barra to speed up talks. Portman said, adding the members are asking for a new product for the plant to build.
Democratic lawmakers told reporters that they focused the meeting on workers. GM says that since 2009 it has invested $22 billion in US facilities.
GM's proposed cuts are planned to take effect in 2019.
The UAW has objected to GM's plan to end production in 2019 at four US plants, saying it violates commitments made during contract talks in 2015.
Administration officials later said they wanted to end subsidies for electric cars in 2020 or 2021, affecting GM and other automakers.
Representative Brenda Lawrence, who represents Detroit, said lawmakers were putting GM was on notice about future production decisions, noting the company is making strong profits and got a massive taxpayer bailout a decade ago.
