Department of Homeland Security Secretary Kristi Noem suggested that changes to the Transportation Security Administration's restrictions on liquids in carry-on bags at airports may be made.

Homeland Security Secretary Kristi Noem has suggested that TSA may soon end its restrictions on liquids in carry-on bags. CBS News senior transportation correspondent Kris Van Cleave has more on that and Transportation Secretary Sean Duffy's plan to overhaul the air traffic control system.

TSA has eased its shoe rule and DHS is now reviewing liquids. A faster screening process may follow, but no official changes have been made.

Transformations in airport security expected as TSA reevaluates checkpoint procedures. New technology could eliminate the need for shoe removal and reduce restrictions on liquid carry-on.

Going through airport security could soon become easier. TSA is now allowing travelers to keep their shoes on and soon may ease the rules on bringing liquids and gels through checkpoints.

The current stipulation is the 3-1-1 rule, which means liquids in carry-on bags must be 3.4 oz or smaller, all contained in a single, clear resealable bag. But that could be changing
