An investigation into abuse of terrorism detainees won't be halted following a letter sent to President Barack Obama by seven former CIA directors. "I don't want to start getting into the business of squelching, you know, investigations that are being conducted," Obama told CNN's John King Sunday.

"I appreciate the former CIA directors wanting to look after an institution that they helped to build," Obama told CBS' Bob Schieffer in a separate interview.
