Remember the, um, slightly ironic biography PublicAffairs released last year? The one about disgraced president Richard Nixon, written by disgraced media baron Conrad Black?

Well, looks like the research Black did for Richard Nixon: A Life in Full may turn out to be useful to him: The Globe and Mail is reporting that the controversial Canadian—who, convicted of fraud in 2007, began serving a six-and-a-half-year prison sentence in March—will go back on his earlier word and ask President Bush to commute his sentence.
