Hillary Clinton will attend a fundraiser Friday with the main financier of Solyndra, the solar firm whose high-profile failure in 2011 embodied much of the Right’s criticism of the green energy industry.

George Kaiser, a major Democratic donor who bundled for President Obama’s campaign, is set to host an event for Clinton Friday afternoon at his Tulsa, Okla. home. His firm, Argonaut Private Equity, was the largest shareholder in Solyndra when the Department of Energy rushed to write the solar corporation a $535 million loan guarantee without first vetting the company, according to the Center for Public Integrity.
