The San Francisco-based group Move America Forward announced its support yesterday for New York lawmakers trying to block U.N. expansion plans in Manhattan.

The organization, which was part of the effort to recall Governor Davis of California, said that working with New York politicians opposed to the U.N.’s expansion was the best way to boot the world body from American soil.

Move America Forward said it also plans to run radio and television advertisements in the New York City market that encourage citizens to help “Get the U.N. out of the U.S.”

The group cited the tax burden placed on Americans as one of their biggest objections to the U.N. expansion.

A Bay Area radio talk-show host and the other co-founder of Move America Forward, Melanie Morgan, said yesterday that, “American taxpayers get soaked twice. First we guarantee the $1.3 billion to renovate their crumbling facilities. Then, the U.S. is expected to pay back 22% of the loan made to ourselves in the form of our annual financial payment to the U.N.”

“We need to send a message to the terrorist sympathizers at the U.N. and let them know that they are no longer welcome on American soil,” Ms. Morgan said.

As the U.N. came under fire from the West Coast, it also met with criticism at home.

A member of the United Nations Development Corporation, Jeffrey Wiesenfeld, which would be responsible for the new 35-story building the world body wants to erect on parts of Robert Moses playground, said that the “way in which [the United Nations] has conducted itself on matters that are near and dear to Americans and the West and Israel” makes it “a deplorable place.”

“Anyone who says it isn’t is not intellectually honest,” Mr. Wiesenfeld told The New York Sun.

He said that the U.N. had in many ways “perverted their ideals.” As a son of two Holocaust survivors, Mr. Wiesenfeld recalls with particular upset the U.N.’s World Conference on Racism, held in Durban, South Africa, at which Israel was denounced as a racist, apartheid state responsible for ethnic cleansing and war crimes.

“I just can’t get over my recollection of Kofi Annan standing there,” Mr. Wiesenfeld said, at what he considered the equivalent of “a Nuremberg rally.”

Despite these criticisms, Mr. Wiesenfeld said that as long as the U.N. exists, it belongs in New York. The UNDC’s role, and his as a member of it, Mr. Wiesenfeld said, is to “facilitate the things that help the U.N. exist here.”

In this role, Mr. Wiesenfeld added, he was defending the city and state of New York, which he said benefit from the U.N.’s economic contribution.

“Having said that,” Mr. Wiesenfeld said, “that doesn’t mean I have to be silent about what I see in the U.N.”

Regarding the action by state senators and other local politicians against U.N. expansion, Mr. Wiesenfeld said, “The U.N. has no one to blame for this but its own membership body, which is predominantly horrible, and its leadership.”
