Actually, the abuse of power was AG Holder and the Obama administration. The order to go after Arpaio was political. Arpaio's "crime" was a misdemeanor and doesn't come close to the pardon of Manning or Marc Rich. Notice how quiet the MSM was about those pardons, and the thousands of criminals pardoned by Obama, whereas now the MSM would have you believe Trump's pardon is an outrageous event. Give me a break. And you believe Trump should be impeached for this "act". Even Democrat politicians (except for the Maxine Waters of the world), would laugh at such an assertion, but they welcome such statements from the public.
