A House hearing is providing new information about the CIA's MKULTRA program, a Cold War-era initiative. Historians have described the experiments conducted under this program as medical torture.

Lawmakers are reexamining the program, raising questions about secrecy and oversight. The hearing is prompting a fresh look at the program's activities and whether similar efforts could be happening.

Further details about the hearing and the MKULTRA program are available from KTXS, the local ABC affiliate in Abilene, Texas.
