Obama mocks Rep. Darrell Issa for 'shameless' turnaround

President Obama hounded California Rep. Darrell Issa for “shameless” behavior while speaking at a Democratic fundraiser in San Diego late Sunday.

Issa has long been a thorn in the Obama administration’s side, especially during his time chairing the powerful House Oversight Committee. As the head of the committee from 2011 to 2015, the California Republican led efforts to investigate the administration’s handling of the Benghazi attacks, the Internal Revenue Service and the controversial “Fast and Furious” gun-trade program in which the U.S. sold firearms to Mexican cartels in an effort to dismantle them through sting operations.
