Donald Trump may be coming to North Texas this week, but the city of Irving says the presumptive Republican presidential nominee can't hold a rally there.

In a statement released Tuesday to NBC 5, a spokeswoman for the city said:

"In consultation with the Irving Police Department, the city of Irving decided it was not given sufficient time – given a 48 hour notice – to gather the resources necessary to ensure the safety and security of those attending such a large scale, high-profile event."

According to Mark Montgomery, the chairman of the Dallas County Republican Party, some republican voters remain timid about supporting the only GOP candidate left in the race for the white house.

“It may take some convincing,” said Montgomery. “There are a lot of ‘never Trump’ people, but it boils down to the fact that…do you want more of the same that we have now? Or do you want some change? We can’t stand to have what we’ve had in the past,” Montgomery said.

The location for the proposed rally was not revealed. Trump is expected to arrive in North Texas from Atlanta, Georgia on Thursday.
