The life of President George H.W. Bush will be honored this week in Washington, D.C. The 41st president's legacy is still felt in American politics more than two decades after he left the White House.

Julian Zelizer, professor of history and public affairs at Princeton University and a CNN political analyst, talks about Bush's legacy.
