Which part of the Tower Commission’s account makes Reagan’s innocence uncertain?

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The part of the Tower Commission’s account that makes Reagan’s innocence uncertain is the part in which the Commission concludes that William Casey -Director of the Central Intelligence Agency (CIA)-should have exerted better control of the operation called "Iran-Contra Affair" to let President Reagan know about the high risks that it included. The Tower Commission also said that US Congress had to be properly informed.

In 1987, under heavy scrutiny, President Reagan appointed the Tower Commission to investigate the Iran-Contra Affair that caused indignity in US politics and the American citizens. In the end, it was clear that President Ronald Reagan was also responsible for the careless management of his subordinates.
