Nixon explains his taped cryptic remark about Helms

[Douglas Caddy]

From the article:  According to a report on the assassination plots made public by the Senate intelligence committee last November, the 1967 C.I.A. report was produced at the request of President Johnson after Drew Pearson, the syndicated columnist, first reported the involvement of the American Government in plots against Mr. Castro'S life.

According to the committee's report, Mr. Johnson was subsequently briefed on the plots that occurred in the Administration of President Kennedy, but not on those in his own.
