ANCHORAGE, Alaska (CNN) - No legal "bombshell" or personal scandal lies behind Alaska Gov. Sarah Palin's resignation, but off-color jokes by talk-show host David Letterman contributed to her decision to step down, Palin's attorney said Monday.
Palin, the Republican vice presidential candidate in 2008, abruptly announced Friday that she would leave office in late July. The decision to resign a year and a half before her term ends, and her rambling, often-disjointed resignation speech, have fueled days of debate among political analysts.
But Thomas Van Flein, Palin's personal lawyer, said no surprises await. The governor needed a break after being "on duty now for two and a half years solid," he said.
"There is no bombshell. There is no shoe to drop. There are no investigations of any type that I'm aware of - no IRS audit, no federal investigation, no state investigation," Van Flein told CNN. "There is no legal reason in terms of a legal problem that compelled the governor to resign."
Friday was "deliberately chosen" for the announcement because of its proximity to the July Fourth holiday, Van Flein said: "She declared her independence from politics as usual."
