pursuing election or supporting a candidate. whether or not bob mueller has ultimately made some case for conspiracy, we don't yet know. as you pointed out correctly, it rests with the attorney general, but the leak by a senior justice department official that there will be no more indictments coming strongly suggests that at least for the narrow charge that robert mueller had, there may be no more everyday forthcoming. i'll join you if you can, briefly, michael, in thanking robert mueller for his service and the professional way if which he's conducted himself. >> the fact that there will be no further indictments doesn't necessarily mean there was not a cog nizable claim against the president or is that a reflection of that justice department policy that says you can't indict a sitting president. i guess what i mean, senator coons is this, might there nevertheless be evidence in that report that rises to the high crimes and misdemeanor standard for impeachment? >> reporter: that's possible.
