Donald Trump was in Michigan on Monday, then his son Donald, Jr. and daughter Ivanka made the rounds.
Now Eric Trump is making campaign stops on behalf of his father on Friday.
Speaking in front of Grace Centers of Hope in Pontiac, a privately owned facility that helps victims of domestic violence and those overcoming addiction issues.
"The problem with Washington is they can't seem to get out of their own way," Eric Trump said. "That's why it's beautiful when you see a place like this and you are so effective at what you do. And you don't have to rely on the federal government."
The younger Trump told supporters his father understands the magnitude of the problem drugs are taking on America.
"Quite frankly I think the things he has seen first-hand the most on the campaign trail, is the hurt and the suffering of individuals and families with addition problems," he said.
Eric Trump's message resonated with voters. And after a brief speech he met with voters and posed for pictures before touring Grace Centers of Hope and meeting some of the people who have gone through the center's rehabilitation program and gotten clean - like Mary Adragna, who now works for the center.
"I was taken to jail because I used to do drugs and sell drugs," she said.
And it's not just the war on drugs that Eric says his father is concerned about.
"Government is not doing much right these days," Trump said. "That's why my father is running for commander in chief."
