U.S. Senator Charles Schumer wants the Transportation Security Administration (TSA) to reverse its newly-announced plan to allow passengers to bring small knives and other items, like golf clubs and hockey sticks, onto planes.

Schumer said the TSA's new policy puts passengers and crew members in danger. He said the items, which were banned after the Sept. 11, 2001, attacks, could be used as weapons.

Schumer is the latest public figure to join a growing opposition to the proposed plan, which is set to be implemented April 25.

Last week, the head of Delta Airlines voiced his opposition to allowing small knives on planes in a letter to TSA administrator John Pistole.

Aviation insurers as well as unions representing flight attendants, pilots and federal air marshals have also publicly opposed the plan. Items like box cutters and razor blades are still prohibited under the new policy.
