As I recall, the US forces allowed journalists with them to cover the war.

Taken from Reporting America at War
In 1968, while anchor of the "CBS Evening News," Cronkite journeyed to Vietnam to report on the aftermath of the Tet offensive. In a dramatic departure from the traditions of "objective" journalism, Cronkite concluded his reports with a personal commentary in which he voiced his strong belief that the war would end in stalemate. Cronkite's editorial would later be regarded as a critical indice of public opinion of the Vietnam War.
In a documentary I saw, Lyndon Johnson had apparently said after seeing that news segment something similar to "If I've lost Cronkite, I've lost the public"
