Thus, A-I was able to provide the CIA soon after

his defection with accurate information regarding DGI

operations and DGI employees in Mexico City.

The Committee has reviewed the CIA's files con-

• cerning A-1. This examination was undertaken to deter-

mine: ])whether A-1 had provided any valuable investiga-

tive leads to the CIA pertaining to the assassination

of President Kennedy; and 2) whether, if such leads were

provided, these leads and/or other significant informa-

tion was made available to the Warren Commission.
