DETROIT (AP) — General Motors CEO Mary Barra joined negotiators at the bargaining table, an indication that a deal may be near to end a monthlong strike by members of the United Auto Workers union that has paralyzed its factories. Barra and GM President Mark Reuss were in the bargaining room early Tuesday, a person briefed on the talks said. But it was not clear if they remained in negotiations, said the person, who didn't want to be identified because the talks are confidential.
