TRENTON - New Jersey's top cop will be answering questions later today about Gov. Chris Christie's use of state police helicopters for transportation.

The Assembly Homeland Security Committee called State Police Superintendent Rick Fuentes to testify after reports that Christie used choppers twice recently to attend his son's high school baseball games.

A political firestorm erupted, and Christie reimbursed taxpayers for the trips.

Committee Chairwoman Annette Quijano says she wants to find out who approves helicopter travel and what the guidelines are for its use.

The governor's office says Christie or his staff used the helicopter 35 times in 16 months, far less than previous governors.

The helicopter fleet is used primarily for emergencies and homeland security missions.

AP wire services contributed to this report.
