Bush Daughter to Wed in Low-Key Ceremony at Camp David Today : First Family: About 100 friends and relatives are invited. It is second marriage for Dorothy LeBlond.

Even political pals such as Dan Quayle and James A. Baker III apparently did not make the guest list for the very private wedding today of President Bush’s only daughter.

The White House has tried mightily to keep all details under wraps, but some have leaked out, including the names of some of about 100 family members and close personal friends who will travel to Camp David, Md., to watch Dorothy LeBlond wed Bobby Koch.

Among those not invited are high ranking Administration officials, including Vice President Quayle and Bush’s longtime friend, Secretary of State Baker, sources said.

“It’s a private ceremony--small, family, close friends,” said Barbara Bush’s press secretary, Anna Maria Perez.

One thing is certain--the nuptials will carry none of the public hoopla that adorned the last wedding in the White House, Tricia Nixon’s marriage to Edward Cox in June, 1971.

It is LeBlond’s second marriage and the first for Koch, a former top aide to House Majority Leader Richard A. Gephardt (D-Mo.).

The only information the White House has released about today’s event are the location--completely out of the limelight at the mountainside presidential retreat located two hours outside Washington--and the minister, Navy Chaplain John Fursti.

In keeping with the nonpolitical theme, Quayle and Baker are excluded, but White House Chief of Staff Samuel K. Skinner made the cut. Skinner’s wife, Honey, is a good friend of LeBlond.

Former Rep. Tony Coelho of California, for whom Koch once worked, was invited, as was Gephardt, Koch’s boss until last week. Gephardt declined the invitation because he has a political fund-raiser in St. Louis with Democratic Texas Gov. Ann Richards.

Bush will give the bride away and she will be attended by her children, Sam, 7, and Ellie, 5. The children are fond of Koch, and attended his Capitol Hill going-away party last week. Koch left Gephardt’s staff to head the Wine Institute’s Washington office.

The Bushes had planned to kick off the wedding festivities Friday night with a black-tie rehearsal dinner for 60 friends and family members at the White House before flying by helicopter to Camp David. Waiters and other staff from the White House are said to be donating their time.
