George Conway and Neil Katyal: “It is high time for Congress to do its duty, in the manner the framers intended. Given how Trump seems ever bent on putting himself above the law, something like what might have happened between him and Ukraine — abusing presidential authority for personal benefit — was almost inevitable. Yet if that is what occurred, part of the responsibility lies with Congress, which has failed to act on the blatant obstruction that Mueller detailed months ago.”

“Congressional procrastination has probably emboldened Trump, and it risks emboldening future presidents who might turn out to be of his sorry ilk. To borrow John Dean’s haunting Watergate-era metaphor once again, there is a cancer on the presidency, and cancers, if not removed, only grow. Congress bears the duty to use the tools provided by the Constitution to remove that cancer now, before it’s too late. As Elbridge Gerry put it at the 1787 Constitutional Convention in Philadelphia, “A good magistrate will not fear [impeachments]. A bad one ought to be kept in fear of them.” By now, Congress should know which one Trump is.”
