“North Korea had agreed to denuclearization. That is certainly a promising step.  Other countries are agreeing to that and continue to endorse our policy and our priorities of denuclearization.  It will be a lengthy process in terms of these conversations and the meetings that we will have with this government… There’s a lot of work ahead of us, a lot of work left to be done”  Heather Nauert, Spokesperson, Washington, DC, June 21, 2018
