"The old rules and old standards of what was considered proper and what was not are less and less abided by," said Jody Powell, who served as President Carter's press secretary. "That's true in all walks of life."
Plenty of press secretaries have written behind-the-scenes views of the West Wing. But such glimpses have traditionally been available only after the president has left office. George Christian, for instance, published "The President Steps Down," about the end of President Johnson's administration, a year after LBJ left the White House.
Others waited even longer. President Kennedy's press secretary, Pierre Salinger, wrote several books about the administration but only after the president's death. The diaries of James Hagerty, President Eisenhower's press secretary, were published after Hagerty died in 1981, a dozen years after Ike's death.
Once the president is out of office, the stories belong to history, said Marlin Fitzwater, who served as White House press secretary under Presidents Reagan and George H.W. Bush and published his memoir in 1995.
"In this day and age, there are so many books, the public hardly blinks an eye on the question of loyalty," Fitzwater said.
Veteran political consultant Tobe Berkovitz, the dean of Boston University's communications school, said loyalty has faded as the image of the White House press secretary has changed. Once a mouthpiece for the president, press secretaries have become political stars in their own right.
Fitzwater dates the trend to 1988, when his predecessor in the Reagan administration, Larry Speakes, published "Speaking Out." The memoir described the president as aloof, cast Vice President George H.W. Bush as a "yes man," and generally created ill will in Washington.
"I have no affection for these kiss-and-tell books," Reagan said at the time.
Speakes ultimately apologized, saying he regretted providing fodder for Reagan's enemies.
During the Clinton administration, political consultant Dick Morris wrote a memoir about the president's reelection campaign. Morris wasn't a press secretary, but White House communications director George Stephanopoulos still wasn't pleased.
"You have a responsibility not to embarrass the president," said Stephanopoulos, who often conducted the daily press briefings and acted as an official spokesman. Yet Stephanopoulos fetched a $2.7 million advance for his 1999 memoir "All Too Human." In it, he said he "felt like a dupe" for defending Clinton's character and painted an often unflattering portrait of the president.
"I think he's probably more comfortable being part of the professional critics of the Washington establishment," Clinton later said.
George W. Bush's first press secretary, Ari Fleischer, published "Taking Heat." Unlike Stephanopoulos or Speakes, however, Fleischer described Bush in favorable terms and saved his harshest words for the media.
"I could have made a lot more money if I'd decided to write about clashes, or criticize the president, or even criticize the press more," Fleischer said after the book's release. "But I chose not to."
