From a cnn.com story on Reliable Sources headlined “Reporters who cover the US military are alarmed by the lack of access right now”:

For decades, American journalists have been granted embed opportunities when American military forces deploy abroad. It has been a long and proud tradition, one that has showcased not only transparency from the US government, but the country’s commitment to a free and open press.

But, with this latest deployment of troops to Eastern Europe, something has gone awry. Reporters have been given no such opportunity to embed with the troops aimed at bolstering NATO as Russia amasses troops along the Ukrainian border. In fact, their many requests have been blocked.
