Harvard has a mid career journalism fellowship. Poland has been sending people there for decades. So has Russia. Even China has sent journalists. Ukraine cannot get its act together.
Journalists apply on their own.
If you want a Ukrainian journalist to become an insider and be on CNN then here is the opportunity. They should be announcing the journalists from abroad this year in March. I doubt that there will be one from Ukraine. They call all these international experts jerks. You know there are other smart people besides Brzezinski.
