EDISON - At least 100 people waited in misty rain and cool temperatures for Republican presidential candidate Donald Trump's campaign office opening in New Jersey.

Trump, who was not at the event, opened his New Jersey headquarters in an Edison office park Tuesday evening.

The crowd of supporters could be heard cheering from outside the event. Reporters were not allowed inside.

New Jersey's primary is June 7, and Trump leads by nearly 30 points in the latest Rutgers-Eagleton poll.

Gov. Chris Christie, who has endorsed Trump and campaigned with him in other states, said Monday he would not attend the event.

Supporters received Trump yard signs and T-shirts that read "Trump: Make America Great Again” at the free event.

The opening comes on the same day Trump won the Republican vote in the Indiana primary.
