In an ironic twist, just moments after Trump requested a "tough primary" for California Senator Dianne Feinstein for leaking the Fusion GPS interview transcript, he is losing California Republican Rep, and the richest member of Congress, Darrell Issa, who announced moments ago that he is retiring and won't seek re-election.

Issa, an influential republican in the House, has been in Congress since 2001, and his most high-profile role was as House Oversight Committee chairman during former President Obama’s presidency, a position he used to hold many hearings on what he viewed as govt misdeeds. Issa, considered the richest member of Congress worth up to $768 million, and his wife ran the nation’s largest manufacturer of vehicle anti-theft devices before selling the co. in 2000.
