Filmmakers would be hard-pressed to sum up Ken Hechler's 93 years in a two-hour documentary.

Besides nine terms in Congress, the West Virginia transplant helped the Allies debrief Hitler's top commanders, served in the Truman White House, marched with Martin Luther King Jr. and wrote a best-seller.

So Russ Barbour and Chip Hitchcock focused on Hechler's efforts to "establish justice" as set out in the preamble to the U.S. Constitution.

The result is "Ken Hechler: In Pursuit of Justice." It premieres 7 p.m. Saturday with a free showing at Marshall University's Memorial Student Center.

The filmmakers conducted more than 50 interviews, pored through archived records from the Truman Library and other sources, and talked to the man himself.

Hechler was elected to Congress from 1958 to 1976. Voters also made him secretary of state from 1984 to 2000.
