The Watch List and MINARET
In its earlier release, the NSA declassified key elements of the story of its Vietnam War-era watch list and the MINARET program, but it held back details on the targets. ISCAP's decision to release the names of some of the prominent persons involved makes it even easier to understand why some NSA officials saw this operation as "disreputable if not outright illegal." (Book III, page 85). It was these concerns that led Attorney General Elliot Richardson to close down the program in the fall of 1973, as the Nixon administration was beginning to unravel. MINARET and other abuse of power, such as NSA Operation SHAMROCK, contributed to the drive for Congressional intelligence oversight and the Foreign Intelligence Surveillance Act (FISA) during the mid-1970s.[3]
What became known as the MINARET program had its basis in earlier efforts to create watch lists initially for suspected threats to the president, for drug dealers, and then, according to the NSA history, for "domestic terrorism." Specifically, in a context of domestic turbulence of 1967, anti-war protests and urban rebellions, President Johnson, angered by the criticism and prone to seeing conspiracies, wanted to know whether domestic anti-Vietnam War leaders and organizations had the support of hostile foreign powers ("Moscow gold"

. Those concerns set in motion the CIA's Operation CHAOS and the NSA's watch list.[4] Those at the FBI and other organizations who helped prepare the watch lists probably found it responsive to presidential wishes to include in the list domestic critics and influential politicians or controversial figures who opposed the War, even if they were not involved in mass protests.
It would be fascinating to see the list of 1,600 or so NSA targets. No doubt, other African-American activists were targeted, as well as the leaders of groups associated with the anti-war protests, e.g. the National Mobilization Committee against the War in Vietnam, Students for a Democratic Society, and the Young Socialist Alliance. Indeed, according to a document at the Gerald Ford Presidential Library, from 1967 to 1973 U.S. intelligence agencies monitored the foreign travel and overseas communications of anti-war and New Left activists such as David Dellinger, Rennie Davis, Jane Fonda, Tom Hayden, Bernardine Dohrn, and Kathy Boudin, as well as prominent African-American militants including Robert F. Williams, Eldridge Cleaver, and Stokely Carmichael. The NSA watch list is not mentioned but it is implicit in the document.[5]
In addition, a number of prominent Americans appeared on the MINARET watch list precisely because in one way or another their thinking dovetailed with the emerging Vietnam War protests. With the intelligence agencies under White House pressure to find out the alleged international connections of anti-war leaders, U.S. intelligence agencies cast a wide net in their efforts to meet the President's wishes. Even the most unlikely names would become targets perhaps because they were prominent, influential, and had expressed what the President considered subversive thoughts. Most, but not all, of the prominent Americans mentioned in the now declassified NSA history fell into this latter category.

I wonder who else the NSA spied on we haven't heard about?
