U.S. Rep. Fred Upton, R-Mich., chairman of the House energy and commerce committee, said U.S. President Barack Obama is dragging his feet with an investigation into a $535 million loan guarantee awarded to Solyndra.
"No matter how hard the Obama administration wishes, this slow trickle of documents will not make Solyndra go away," Upton said in a statement. "Taxpayers are out half a billion dollars and we must ensure more Solyndras never happen again."
In its document release, the White House handed over more than 450 pages of internal documents related to a November subpoena.
Upton said that wasn't enough, however. He said the White House has until Tuesday to deliver "all Solyndra-related documents."
Upton said last week, however, he appreciated the "willingness to comply" when authorities with the Office of Management and Budget agreed to testify in the Solyndra probe.
Obama touted the company as a centerpiece of his green economic agenda prior to the company declaring bankruptcy in 2010.
