Honda Motor Co. said Wednesday it will expand a recall campaign across the United States for vehicles equipped with air bags produced by Takata Corp., which is under fire for defects linked to multiple fatalities.

In a U.S. congressional hearing, Takata promised to cooperate with U.S. safety regulators on the issue but stopped short of agreeing to a nationwide recall, citing a lack of post-accident information.

"We want to tell you that Honda will be expanding our campaign to nationwide," Rick Schostek, executive vice president of Honda North America Inc., told a panel under the House of Representatives' Committee on Energy and Commerce.
