The Federal Aviation Administration is considering temporary flight reductions in and out of Newark Liberty International Airport, and it's launching a safety task force.

At times Monday evening, as few as three air traffic controllers per hour were lined up to monitor via radar the planes flying into and out of the airport, the Federal Aviation Administration said.

Staff shortages and equipment failures at Newark Liberty International Airport have raised safety concerns in recent weeks.

Transportation Secretary Sean Duffy says a new software update prevented a third radar outage over the last two weeks at New Jersey's busy Newark airport when a telecommunications line failed again over the weekend.

Sen. Andy Kim, a New Jersey Democrat, said the FAA is not being transparent enough after visiting air traffic controllers in Philadelphia and Newark.
