On Tuesday night, Marco Rubio gave a must-see speech — and much needed reminder — on the Senate floor of why the Founders created such standards of decorum for the upper chamber.

Watch the inspiring reminder here:

Some of the senator’s best remarks had to do with reminding everyone why the framers of the legislative branch decided that personal attacks could not be  countenanced in the Senate.

“I think what’s at question here is perhaps one of the very reasons why I ran for this body to begin with. Maybe it’s because of my background, I’m surrounded by people that have lost freedoms in places where they’re not allowed to speak. One of the great freedoms of our nation is the ability to come forward and have debates. But the Founders, framers, those who established this institution and guided it for over two centuries understood that that debate was impossible if in fact the matters became of a personal nature.

I want people to think about our politics here in America, because I’m telling you guys that I don’t know of a single nation in this history of the world that’s been able to solve its problems when half the people in the country absolutely hate the other half of the people in that country. This is the most important country in the word, and people in this body cannot function if people are offending one another and that’s why those rules are in place.

The linchpin of that debate is the ability of this institution through unlimited debate and the decorum necessary for that debate, to be able to conduct itself in that manner. And so, I know tonight was probably a made for T.V. moment for some people. This has nothing to do with censoring the words of some great heroes. I have extraordinary admiration for the men and women who led the civil rights effort in this country.

We would do well to remember that Sen. Warren was rightly voted off the Senate floor for violating Rule 19. The Democrats can bellyache and fundraise all they want, but these rules are there for good reason and have served us well.
