This is the big celebrity wedding weekend when Andrew Cuomo and Kerry Kennedy join political dynasties. Several members of both Democratic families are expected at the private wedding here early Saturday afternoon in St. Matthew's Cathedral, where President John F. Kennedy's funeral was conducted in 1963. The wedding reception, also private, will follow at Ethel Kennedy's home in McLean, Hickory Hill.

Cuomo, 32, the son of Gov. Mario and Matilda Cuomo, in addition to being his father's closest adviser, runs Housing Enterprise for the Less Privileged (HELP), which builds housing for the homeless in New York State. Kennedy, 30, the daughter of Robert and Ethel Kennedy, is executive director of the Robert F. Kennedy Memorial Center for Human Rights. After the wedding she will move the center to New York, where the couple will live.

Out and About The Cuomo-Kennedy wedding falls just a few days after the 22nd anniversary of the assassination of Sen. Robert F. Kennedy. His brother Sen. Edward M. Kennedy paid a visit to RFK's Arlington National Cemetery grave site yesterday, the anniversary date. Kennedy stood alone at the grave, his head bowed. He laid a flower there and then paid a visit to John F. Kennedy's grave nearby ...

A 42-year-old resident of the Virgin Islands was arrested yesterday for throwing a small sheaf of papers that hit Vice President Dan Quayle in the head. Quayle was unhurt and was whisked away in his limousine. The vice president was coming out of the Hart Senate Office Building when the man shouted something about having documents and threw them. The Secret Service identified the man as Mwenea Sikuzote, of St. Thomas. He is charged with the federal crime of assaulting a vice president and if convicted could be sentenced to 10 years in prison and fined $10,000. One of the papers seemed to be a letter to President Bush and Soviet President Mikhail Gorbachev ...

In what apparently was a very private ceremony, U.S. Rep. John Conyers, 61, on Monday married Monica Ann Esters, 25, of Detroit. The Michigan congressman's aides in Washington, workers at his Detroit office and even his brother, a Detroit auto dealer, said they knew nothing of the marriage, which is on record at the Wayne County Clerk's Office ...

Times certainly have changed. When Leonid Brezhnev and Richard Nixon met for a summit visit, the former Soviet leader went home with a Lincoln Continental as a gift. When Mikhail Gorbachev left Washington after last weekend's summit, his gift from President Bush was the five-volume "Life of George Washington." Another gift from the president was an orange horseshoe mounted on a wooden plaque. It seems it was the same lucky shoe Gorbachev tossed for a first-time ringer at Camp David. It isn't a shiny new car, but then you can't hang a car on the rumpus room wall ...

Madonna fans might be getting nervous. The rock star canceled a Wednesday concert in Worcester, Mass., on doctors' orders because of lingering throat problems. A physician told her that unless she took several days off, she risked permanent damage to her voice and vocal cords, forcing her to cancel her third Worcester show, slated for yesterday. Madonna is scheduled to appear Friday and Saturday at Capital Centre. Cellar Door Productions, the booker of the Washington concert, was still saying yesterday that Madonna would be here ...

Actor Ron Silver's rambling support of the National Endowment for the Arts at the Tony Awards Sunday night, and his reminder of the bloody events in Tiananmen Square in Beijing, brought him a reprimand from the show's producer, Joseph Cates. During a commercial break, Cates told Silver his speech was inappropriate and then told the audience: "I support the NEA {but} to take advantage of a live TV show like that does us all incredible harm. This is not the show on which to make those comments." As to why there was no mention of the death of international star Rex Harrison at the awards, Cates said he simply didn't have enough time to pull together a fitting tribute ...
