Two House Republicans sent a letter to the president's lawyer Wednesday requesting all communications among White House staff and officials relating to Solyndra's $535 million federal loan guarantee.
Rep. Fred Upton of Michigan, the chairman of the House Energy and Commerce Committee, and Rep. Cliff Stearns of Florida, the chairman of the committee's Oversight and Investigations Subcommittee, asked for all documents dating back to Obama's 2009 inauguration.
Their request came two days after Democrats on the committee released email excerpts that revealed that senior presidential advisors brushed aside warnings about solar panel maker Solyndra's shaky finances ahead of President Barack Obama's May 2010 visit to the company.
The committee has been investigating Solyndra's Department of Energy-backed loan guarantee since February 2011, seven months before the company went bankrupt.
In a statement Wednesday, Stearns referenced and raised concerns about the "startlingly cozy relationship between wealthy donors and the President's closest confidantes," adding that "some of the loudest alarm bells on Solyndra's viability" came from within the administration.
Democrats on the committee had released the email excerpts to counter Republican claims that the White House rushed approval of Solyndra's loan because a lead investor in the company had ties to a major contributor to Obama's 2008 presidential campaign. The full text of the internal emails, released Tuesday, is available here.
Wednesday's letter set a deadline of Oct. 14 for the White House to produce the additional documents.
