Rep. Darrell Issa (R-Calif.) said Tuesday that his committee plans to investigate government loan programs to private corporations in light of allegations of improper dealings between the White House and failed energy company Solyndra and wireless start-up LightSquared.

“I want to see when the president and his cronies are picking winners and losers… it wasn’t because there were large contributions given to them,” the chairman of the Oversight and Government Reform Committee said Tuesday morning on C-SPAN.

Issa said the committee was looking at whether it was improper for members of Congress or White House staff to select companies eligible for subsidized government loans when those companies could give campaign donations. Loan programs have been a popular tool to provide funding for popular industries — like tech, green energy, and American auto companies — at more favorable terms than could be secured privately.

The Obama administration has been defending itself against criticism by Republicans that it exerted improper influence to the aid of both companies.

Solyndra abruptly filed for bankruptcy earlier this month, surprising both employees and the administration, which had secured $535 million in low-interest loans for the company.

Republicans in Congress quickly mocked the bankruptcy as emblematic of the president’s green technology initiatives under the stimulus bill — and noted that a key Solyndra investor had been a bundler for the Obama campaign. House Republicans say they have emails showing the White House pressuring Department of Energy bureaucrats to expedite the loan approvals, although the White House has argued that nothing improper occurred.

Republicans have also charged that the White House pressured an Air Force general to revise testimony before a closed congressional hearing to aid LightSquared, a wireless start-up company. Emails between the company and the White House make mention of the fact that the company’s CEO would be attending Democratic fundraisers in Washington, and administration officials met with executives from the company on the same day that CEO Sanjiv Ahuja wrote a $30,400 check to the Democratic National Committee.
