Hodel Backs New Vietnam Statue Interior Secretary Donald Hodel announced his support this week for having a statue placed near the Vietnam Veterans Memorial to honor women who served in that war.

Hodel has informed Congress of his support and within two weeks will forward a recommendation to the U.S. Commission of Fine Arts and the National Capital Planning Commission, both of which review memorial proposals for the federal government.

"American women made outstanding contributions to the Vietnam war and I believe that a tribute in the form of a commemorative statue should be created in remembrance of their participation," Hodel said in a statement.

Trudeau's Pointed Pen Cartoonist Garry Trudeau, who usually lets his "Doonesbury" comic strip do the talking for him, went public with a rare interview this week with the South China Morning Post in Hong Kong. The paper quoted Trudeau as saying the policies of President Reagan have "helped us to evolve from a country which wanted to do good into a country which wants to feel good." The cartoonist described his "investigative cartooning" as "really an expression of a corny kind of patriotism" and said the strip's popularity outside the United States "just baffles me."

Lincoln Documents Found Workers renovating the Springfield, Ill., home of Abraham Lincoln discovered documents dating back to his days as a congressman in the 1840s, a historian said.

Among the documents, found in a kitchen wall, were part of an envelope addressed and signed by Lincoln, four letters to Lincoln and a printed antislavery speech. They eventually will be displayed at the home, which is undergoing a $1.7 million renovation to be completed next spring. About the discovery? "We're not going to have to rewrite the history books, but we will have the opportunity to gain some fresh insights into Lincoln's congressional period," said site historian George Painter.

A contract signing to confirm the book deal is scheduled for next week. A source close to Whitehead told The Record of Hackensack, N.J., that she will receive an advance of about $95,000.

Berry's Hollywood Duck Walk Rock 'n' roll legend Chuck Berry did his signature "duck walk" Thursday to the cheers of hundreds of fans who watched the unveiling of his star on the Hollywood Walk of Fame.

The dedication ceremony in Los Angeles was held in connection with the release of the Taylor Hackford documentary "Chuck Berry Hail! Hail! Rock 'n' Roll!" To many of Berry's fans, the recognition for the 60-year-old rocker was way overdue. "I've been dancing and listening to his music since I was a teen-ager. I love rock 'n' roll," said a 47-year-old fan.

Berry's eyes became teary as fans shouted, "We love you, Chuck!"

"I am not a speaker. I write songs, and they tell me I wrote a book, although it took me seven years," he told the crowd. "Now I'm in a movie. I'm so excited I don't know what to do. I love you. I love rock 'n' roll!"
