The Park Service has been allowing World War II vets who have traveled from all over the country to enter the memorial, but the rest of the public is barred due to the budget battle.
In the video from NBC Washington, Neugebauer can be heard saying, "How do you look at them .. and deny them access? … the Park Service should be ashamed of themselves."
The unnamed park ranger can be heard replying back, "I'm not ashamed."
Neugebauer, along with almost all House Republicans, voted for a funding measure that would also delay The Affordable Care Act. That vote helped set up a showdown with the Senate and President Barack Obama.
With no agreement on how to fund the federal government, non-essential government functions have shut down.
"It's difficult," responded the Park Service employee.
An onlooker is then heard yelling at the congressman, "This woman is doing her job, just like me. I'm a 30-year federal veteran -- I'm out of work."
