Maybe, although Carney has denied it.
It certainly wouldn’t surprise me if it happened. And Carney’s disclaimer is more or less irrelevant; he has no credibility left. However, it hardly matters if they get the questions ahead or not, because the MSM is so in league with this administration that the White House pretty much knows that it’s not going to really be challenged, either with difficult questions or with follow-ups to the answers it provides. The press is almost wholly under the administration’s thumb anyway.
So in essence, as a leading light of the Democratic Party would say, “What difference at this point does it make” whether they get the answers in advance or not? It would be merely a slight intensification of something we already know to be true.
