By BRETT ZONGKERWASHINGTON (AP) â¿¿ The future of a planned memorial honoring Dwight D. Eisenhower was thrown into doubt Tuesday as lawmakers questioned the project's design and cost and the 34th president's family called again for the memorial project to be redesigned. A House panel hosted a hearing on the 14-year-old project, which is planned for a site on the National Mall near the National Air and Space Museum. Planners could lose that space, though, without an extension soon from Congress. For more than a year, the memorial's design by architect Frank Gehry has been criticized by some for its "avant-garde approach" to memorial architecture and praised by others for its innovative elements. Gehry proposed a memorial park for Eisenhower with statues of the two-term president and World War II hero â¿¿ framed by large, metal tapestries depicting a Kansas landscape from his boyhood home. On Tuesday, Eisenhower's family threw its support behind new legislation in Congress that would scrap the design, start a new design competition and block any more federal funding for the current concept. Already about $60 million has been allocated for the $142 million project. Eisenhower's family has objected to Gehry's design, calling it "too extravagant" â¿¿ in particular the metal tapestries held up by 80-foot-tall columns. "Continuation of the status quo ... will doom the prospect of building a memorial," said Susan Eisenhower, the president's granddaughter. "It is time to go back to the drawing board, with an open process for the redesign of the memorial." The family, she said, supports new legislation from Utah Rep. Rob Bishop that would redirect the project. Susan Eisenhower said she knew of no other presidential memorial built over the objections of the president's family. She called for an open accounting of all the money spent so far and an outside review of the project's management.
