CNN — The liquid rule for carry-on bags could be the next airport security measure to be overhauled. Kristi Noem, Secretary of the Department of Homeland Security, hinted at a possible policy change on Wednesday at the Hill Nation Summit hosted by The Hill and NewsNation in Washington.

“But I will tell you — I mean the liquids — I’m questioning. So that may be the next big announcement is what size your liquids need to be,” Noem told NewsNation’s host Blake Burman.

Noem’s comments came shortly after DHS rolled back a rule in place for nearly two decades requiring travelers to remove their shoes at Transportation Security Administration checkpoints. The DHS oversees the TSA, which was established after the terrorist attacks on September 11, 2001.

The TSA’s 3-1-1 liquids rule — which requires that liquids in carry-on luggage be limited to 3.4 ounces or less and stored in a single, one-quart, resealable plastic bag — was introduced in September 2006. The rule was established shortly after a terrorist plot to detonate liquid explosives on transatlantic flights was foiled by British police, according to an official TSA timeline.
