The GOP spineless wimps would never call for an investigation.
Bad idea. Better that the investigation is handled by the newspapers, blogs and actual law enforcement for now. A congressional investigation by a democrat-run congress would produce nothing but additional cover to this criminal operation.
They’d posture and twist this into a Republican scandal. They’d be entitled to subpoena the records of the RNC and anyone with an R after their name to check for “irregularities”, while having access to the info the FBI and FEC and other invesitigators have on their crooked friends and the connections to China, which they’d then scurry off to disappear any trace of from their own records.
