The future of a planned national memorial honoring President Dwight D. Eisenhower in Washington is up for debate in Congress.

A House panel is hosting a hearing Tuesday on the project. For more than a year, the memorial’s design by architect Frank Gehry has been criticized by some and defended by others.

Susan Eisenhower, the former president’s granddaughter, will testify for the family Tuesday. Retired Brig. Gen. Carl Reddel, the executive director of the federal Eisenhower Memorial Commission, also is scheduled to testify, along with California Rep. Darrell Issa, who has been questioning the project’s spending and design process.

A new proposal in the House calls for a new design competition and would block future funding for Gehry’s design. Millions of taxpayer dollars have already been spent on the project.
