Ray McGovern, who was in the CIA for twenty seven years asked him why he lied about the run-up to the Iraq war. Rumsfeld then proceeded to lie to McGovern to cover up his earlier statements about WMD's being in Iraq. He also tries to use the troops in his defense, a terrible strategy, but not uncommon unfortunately. Notice, at the end of the clip, Ray gets vilified for asking Rumsfeld some pointed questions. We can't have that, no-no-no.
