LOUISVILLE, Ky. (WDRB) -- The biggest NRA convention ever is about to begin in Louisville with 80,000 people attending -- and traffic is tight.

Trimarc, as well as WDRB reporter Valerie Chinn, is reporting that traffic is backed up on the interstate leading to the fairgrounds.

Attendees will hear from a long list of high-profile political figures like Mitch McConnell, Marco Rubio, Matt Bevin and Mike Pence. But likely no one will cause as much of a stir inside and outside Freedom Hall as Republican presidential candidate Donald Trump.

When Trump takes the stage, he'll face a much friendlier crowd than the one that greeted him during his campaign stop at the convention center in March.

NRA spokesperson Amy Hunter can't wait.

"The Second Amendment is a really important issue that I think they know their voters and constituents really care about," Hunter said. " And this is a great forum for them to come out and talk personally about an issue that really matters to a lot of Americans."

However, protests are expected outside Freedom Hall.

And Democratic congressman John Yarmuth is hoping people turn out in large numbers.

"I hope that, during his appearance in Louisville, there will be an enormous outpouring of opposition, both to the NRA and to his brand of politics," Yarmuth said.

Yarmuth says Trump's speech to the NRA is yet another example of his pandering to what he calls the worst instincts and most polarizing and extreme elements of society.

"The NRA ... is totally out of touch with the attitudes of the vast majority of American people about common sense approaches to gun violence, including universal background checks and closing the gun show loophole, among others."

The leadership forum gets underway at 12:30 p.m Friday at the Kentucky Exposition Center.

You do have to buy a ticket and have a minimum of an associate membership to attend. You can purchase tickets here.
