They share the same name but this Trump likes to be called Don. He was at a Women for Trump event in Brookfield Wednesday morning.
"Hillary's biggest knock on my father is that he doesn't have experience," Trump Jr. said. "What has her experience got us?"
His father's tax records have gotten a lot of scrutiny. The New York Times reported the billionaire businessman took a $916 million dollar loss as a tax right off in 1995 -- suggesting he could have avoided paying federal income taxes for years.
Benson: Do you think the Clinton campaign is misleading when they say your father does not pay federal taxes?
Trump Jr.: Of course they are misleading.
The Trump team said he has paid federal taxes but there's no clarity. Trump is the first presidential nominee in 40 years not to release his tax returns. Trump Jr. said his father did nothing wrong by taking the massive tax deduction.
"What my father did is he utilized the tax code to save his company. To keep the people he employs, the tens of thousands of people he employs, to keep them employed," Trump Jr. said.
Trump lost big in Wisconsin during the April primary. No Republican presidential candidate has won Wisconsin in November since Ronald Reagan in 1984.
Benson: How does your father close the deal with Wisconsin voters and Wisconsin voters who are hesitant, they didn't vote for him the first time around?
Trump Jr.: They have to look at the long-term ramifications. It's just about the presidency. If you lose the Supreme Court you are going to have liberal justices legislating from the bench for the next 30 or 40 years
