Wauwatosa West High School invited Senator Ron Johnson (R-Wisconsin) to speak to its AP Government and Politics class.
His main message to students was blunt: appreciate the educational opportunities you've been given, and don't screw them up.
"Don't do drugs," Sen. Johnson added. "I was in the White House yesterday when President Trump announced he was going to call this opioid overdose problem at national emergency."
When the senator opened it up to questions, students asked his thoughts on various topics such as Sen. Jeff Flake (R-Arizona) questioning President Trump's ability to lead.
"I'm not going to comment on what one senator chooses to say or how they want to conduct themselves," said Sen. Johnson. "I'm just responsible for my own words, my own actions."
Students also asked for his take on standing for the national anthem.
He replied, "There's a tried and true way of respecting that flag. It's called standing at attention with a hand over your heart. That's what I'd like to see at every sporting event."
Students like Jade Grippe, a senior, said she and fellow seniors do talk about politics, "It's just interesting to see people at such a young age care about politics and care about what's going to happen to us in the future."
They were grateful for Sen. Johnson's visit.
"It was a really cool experience," said Bennett Inman, a senior. "It's really interesting to see one of 100 people that represents us in the federal government."
When the students and senator finished their Q&A students got the chance to talk and take pictures with Senator Johnson.
