A group of House Republicans is pressing the Department of Energy for details on a loan program that has come under fire for its assistance to a number of failed green companies.

Five GOP leaders of the House Energy and Commerce Committee are pushing the department to give details about apparent discrepancies between the number of advertised and realized jobs created by the government program, which provides loans for some renewable energy projects.

In a letter, the representatives assert that expected jobs “have failed to materialize,” yet the Energy Department has not updated its website to reflect the jobs estimated to be created or saved by the program.
