The government invested $2 billion more in General Motors Corp. this week as the auto giant was still struggling in possibility of bankruptcy and trying its efforts to restructure.

The Treasury Department said Friday it lent the additional money to GM on Wednesday to provide working capital. The loan pushes the total amount of GM’s government aid to $15.4 billion after the company said it would need more money in the second quarter to stay afloat.

A government report revealed earlier this week that the Treasury was prepared to provide GM with up to $5 billion more in federal loans and Chrysler with up to $500 million more in bailout support as they race against deadlines to restructure.
