Watch Clinton's First Lady: Hillary on PBS. See more from American Experience.

A PBS Bill Clinton documentary premieres over two nights on Monday and Tuesday. The total viewing time is four hours. Rahm Emanuel, who was with Clinton from his 1992 campaign in Little Rock, Ark., through his impeachment, was not one of the Clinton-era figures interviewed for the project. PBS said Emanuel was not approached because at the time the documentary was being made, he was President Barack Obama's Chief of Staff. The documentary makers had several other people at his level from the Clinton White House, so they did not approach the now mayor of Chicago.
