Jon Meacham on Russia Investigation: Key Question Is Will the 40% of Trump Supporters Accept Anything Against Their President

EXCERPT:

MEACHAM: "To my mind, one of the most interesting things at this point here on the — as we head into early summer, is you have these two tracks going. You have Mueller and the legal track, but you also have the inexorable march of time on the political track headed toward the midterm, headed toward the possibility, the likelihood that the House of Representatives is going to be in Democratic hands come January. And as Gerald Ford once said, an impeachable offense is whatever the majority of the House of Representatives says it is at any given time. So there are two trains heading into the station, if you will. And I think the key question for the country is will the 40 percent, 35, 40 percent of Trump supporters who decline at any point to accept anything against their president, if the facts emerge, will they accept those facts or are we going to have a tribal battle to the very end of this thing?”
