A day after the FBI raided the Fremont headquarters of Solyndra, agents expanded their search to the company's CEO and two of its executives.
The FBI sent agents to the homes of CEO Brian Harrison and company founder Chris Gronet and a former unnamed executive, according to ABC News.
Thursday's FBI investigation was prompted by a request by the Department of Energy's inspector general, FBI spokesman Peter Lee said.
Agents arrived at Solyndra at 7a.m. and were examining the factory.
Solyndra filed for bankruptcy last week, shocking both workers and the Obama administration, which had given the startup $535 million in low interest loans.
The announcement was a devastating blow to Mr. Obama who is set to deliver a speech on job creation Thursday evening.
Congress has demanded a hearing into the matter. Wednesday the company was reported to be for sale.
There are no reports of any arrests at this time.
Solyndra officials made numerous visits -- 20 -- to the White House, according to logs and reporting by The Daily Caller.
