The Transportation Security Administration will delay its plan to allow small knives on planes.
It was set to go into effect Thursday.
The plan received backlash from some airlines, flight attendants, pilots and air marshals.
Some lawmakers, including Sen. Charles Schumer and Rep. Michael Grimm, have also spoken out against the proposed rule change. They are working in conjunction with several other lawmakers on a bill to permanently ban knives from planes, according to the Association of Flight Attendants.
Some opposed to the initiative said the TSA should have given the public a chance to voice its opinion on the new rule before a decision was made.
The TSA said last month that with new security measures, it is unlikely a small knife could be successfully used by terrorists to take over a plane again.
In addition, the TSA said security officers need to be able to focus on larger items at security, and focusing on smaller items only serves as a distraction.
Small knives were initially banned on planes after the September 11th attacks.
By Monday evening, TSA officials had not commented on the policy reversal.
