New York officials say new security plans for the Statue of Liberty could leave visitors vulnerable to terrorism when the island reopens on July Fourth.
The National Park Service has decided to move security screening to Ellis Island.
Sen. Charles Schumer and New York Police Commissioner Raymond Kelly say that decision should be reversed.
Previously, passengers were screened before they boarded boats at Battery Park in Lower Manhattan and Liberty State Park in New Jersey.
The statue was closed after Superstorm Sandy flooded Liberty Island in October.
Park service representatives did not immediately respond to comment requests on Monday.
