WASHINGTON, May 5 (Reuters) - Senate Democratic Leader

Chuck Schumer on Monday called for a probe into a probe into

ongoing flight disruptions at Newark airport outside Manhattan

that have disrupted hundreds of flights over the last eight days

because of equipment and staffing issues.

United Airlines CEO Scott Kirby on Friday that the

carrier will begin canceling 35 additional flights a day - or

about 10% - at its Newark hub. Schumer asked the Transportation

Department Office of Inspector General investigation "into what

happened at Newark so these problems don't get worse, or spread

to airports across the nation."
