Donald Trump reiterated his pitch for improving the lot of veterans during a brief appearance Sunday before thousands of bikers at the Rolling Thunder rally in Washington, D.C.

The annual Memorial Day weekend rally draws tens of thousands of motorcyclists, many of them veterans, to pay homage to fallen heroes and raise awareness of veterans' issues. One issue has been interminable waits for medical service at VA hospitals.

The presumptive Republican presidential nominee said that, if elected, he would ensure that veterans could opt for private physicians, "and we'll pay for it."

"Thousands of people are dying, waiting in line to see a doctor," Trump told the crowd. "That is not going to happen anymore."

Trump hit on several other familiar themes, including construction of a wall along the Mexican border.

"We are going to have a real wall," Trump told the enthusiastic crowd. "And who is going to pay for it?!"

"Mexico!" the crowd roared in response.

Trump also promised better international trade deals, an end to Obamacare and victory over the Islamic State, also known as ISIL or ISIS. He provided few details.

"We have to rebuild our military. It’s been decimated," Trump said. "We are going to beat ISIS. We are going to knock the hell out of them."
