Taylor Branch , the Pulitzer Prize-winning author and civil rights historian, would pick up a notepad of questions and two microcassette recorders and drive his truck down Interstate 95 to Washington. Parking on the South Lawn, he would head to the White House family quarters for interviews so secret Clinton stored the tapes of them in his sock drawer.

What followed sometimes seemed like one of the bull sessions the two had two decades earlier when they shared an apartment in Austin, running George McGovern's 1972 presidential campaign in Texas .

In these interviews and a new book that has followed, Branch says he tried to capture Clinton's unvarnished perspective on the events swirling around his presidency, from the consequential to the occasionally comic.

Reluctant to discuss the affair with Monica Lewinsky that led to his impeachment, Clinton once lamented that it occurred when he felt sorry for himself and that he "just cracked" under the pressure of personal and political setback.

He also relayed how Boris Yeltsin 's late-night drinking during a visit to Washington in 1995 nearly created an international incident. The Russian president was staying at Blair House, the government guest quarters. Late at night, Clinton told Branch, Secret Service agents found Yeltsin clad only in his underwear, standing alone on Pennsylvania Avenue and trying to hail a cab. He wanted a pizza, he told them, his words slurring.

The next night, Yeltsin eluded security forces again when he climbed down back stairs to the Blair House basement. A building guard took Yeltsin for a drunken intruder until Russian and U.S. agents arrived on the scene and rescued him.
