ambassador, i'd like to direct you to another line of questioning that i had for ambassador taylor earlier this week. he said that there were irregular channels of diplomacy at work in ukraine circumventing normal diplomatic channels and threatening american interest in favor of private interest. i asked him the question, can you rule out the possible -- possibility that these irregular channels of diplomacy are being used in other countries where we conduct foreign policy? in response, he said that he could not rule it out. ambassador yovanovitch, i ask you and i assume that you can't rule it out either, correct? >> i can't but i would also add i have no knowledge of that. >> i understand. are you concerned that these irregular channels of diplomacy may be at work elsewhere? >> i think it's a possibility. >> you testified that it was a quote/unquote dangerous precedent that private interests and people who don't like a particular ambassador could combine to replace that
