What happens to all those former Cabinet secretaries, who once had cars and drivers, the ear of the president and, in some cases, Secret Service protectors? Mostly, they're still around and generally don't get invited out so much anymore. Some 30 current and former Cabinet secretaries will be at a luncheon at the Madison Hotel today of the President's Cabinet Club. The club is a reorganization of an informal gathering of President Reagan's Cabinet secretaries, who began meeting on an irregular basis in 1981. At that time, it included Vice President George Bush and its organizer, Agriculture Secretary John Block.

The new club, put together by Block and Madison Hotel owner Marshall Coyne, will for the first time include former Cabinet officers as well as current ones. The present and former secretaries, with spouses, representing several administrations, will dine together at what is to become an annual event. Expected to attend are Orville L. Freeman, Elliot Richardson, Richard Schweiker, William P. Rogers, William Webster, Ann Dore McLaughlin, Edwin Meese, Al Haig, W.J. Usery, Margaret Heckler, Richard Cheney and Ray Marshall.

'Tis the season: Sen. Ted Kennedy is always on top of the news, even when he's having fun. Each year at his annual office party he dresses up as someone in the news. In 1987, he was the Iran-contra hearings star Fawn Hall, complete with documents stuffed in his bra. In 1988, he was a credible Elvis, and last year he showed up as the Caped Crusader himself and observed: "That's Batman, not fat man." At last week's Christmas party, the Massachusetts Democrat was dressed up in long braids, gold earrings and tights as half of the Grammy-winning, non-singing rock group Milli Vanilli. "I'm Vanilli," he explained, "because Millie is in the White House." Apparently you had to be there, and if you weren't, you'll never see a photograph because cameras were banned. It's nice to know that it isn't all budget crisis talk and concern about Saddam Hussein on Capitol Hill ...

After all that tough politicking, the National Press Club has a new president: Kathryn Kahler, Newhouse News Justice Department correspondent. She beat John Peterson, national correspondent for the Detroit News. During the campaign, Peterson supporters produced a slick campaign brochure, and Kahler, knowing what journalists really want, promised to open another lounge at the Press Club with drinks and quality hors d'oeuvres. That's clearly how she got elected president. She is only the fourth woman to head the 83-year-old club ...

Now that Donald Trump has his divorce, will Marla Maples really be the next Mrs. T? Obviously that's not so certain as it once seemed. Trump has been seen lately with another sexy blonde, 23-year-old former "Star Search" contestant Rowanne Brewer. What it all means might be read in what Marla's publicist Chuck Jones had to say about Rowanne in the recent People magazine. "She more or less fits the bimbo image. Her whole life seems to be just swimsuits." And to think Trump seems to be passing up nuclear scientist Marla for bimbo Rowanne ...
