NEWARK - Passengers have faced long lines at security checkpoints at Newark Liberty International Airport and many others over the past few weeks.

The problems have gained the attention of the head of the Transportation Security Administration, and he says changes are on the way.

TSA Secretary Jeh Johnson says he’s noticed the delays in Newark and at airports around the country so he's making some changes he believes will get people through security more quickly without jeopardizing safety. 

The changes include increased staffing, expanded efforts to enroll people in TSA Pre-Check and working with airlines and airports to support non-screening options.

Johnson also called on congress to approve more funds to pay for additional screeners during peak periods at high-volume airports.
