Why was Nixon so fixated on prosecuting Ellsberg? In other words, what did he fear about Ellsberg?

Explanation:

Nixon feared about be exposed by Ellsbeg. The Pentagon Papers were released by Daniel Ellsberg, the papers revealed that the U.S. had secretly enlarged the scope of its actions in the Vietnam War with the bombings of nearby Cambodia and Laos, coastal raids on North Vietnam, as well as Marine Corps attacks, none of which were reported in the mainstream media. For this Ellsberg was charged with conspiracy, espionage, and theft of government property, but the charges were dropped after prosecutors started investigating into the Watergate scandal in which Nixon had ordered the Special Investigations Unit to do unlawful things to discredit Ellsberg.
