May 6 (Reuters) - The U.S. Transportation Department is

working with airlines to cut flights at New Jersey's Newark

International Airport and boost air traffic staffing after

hundreds of flights have been disrupted since April 28,

Secretary Sean Duffy said on Tuesday.

Duffy told CNN the department is in the process of bringing

together the airlines that serve Newark and "having a

conversation about how they reduce their capacity in Newark."

The airport has been hit by runway construction, government

equipment outages and air traffic control staffing shortages.
