WATCH: Obama responds to heckler while speaking out against attack on Nancy Pelosi's husband

During a Democratic political rally in Detroit on Saturday, former President Barack Obama was interrupted by a heckler after he remarked on the assault of Nancy Pelosi's husband.

During his first presidential campaign in 2008, Barack Obama called for bipartisanship and spoke of the need for civility.

We start demonizing people when we don't agree with them. The former president said that creating a dangerous climate was caused by that. If elected officials don't do more to explicitly reject that type of rhetoric, if they tacitly support it or encourage their supporters to stand up inside voting places armed with guns and dressed in tactical gear, more people can get hurt. The basic spirit of this country will be violated.

The heckler yelled at the former president after he called on lawmakers to reject dangerous rhetoric.

The heckler's voice was inaudible for most of the exchange.

The crowd began to chant "Obama" to drown out the protestor, as the former president tried to speak with the man in a way that was respectful of both of them.

"Come on, sir," Obama said. This is what I'm talking about. We have a process in our democracy. I'm having a conversation right now. Soon, you'll have a chance to speak. We don't have to yell at each other. It isn't a good way to conduct business.

In a workplace, you wouldn't do that. People are talking in the middle of a conversation. We don't do things like that. This is one of the things that I want to say. Basic civility and courtesy is what we are trying to encourage.

The crowd became restless with the heckler's conduct and a security team escorted him out of the gym.

Obama told them to hold up. Don't stop, hold up. Let's hold on for a second.

The crowd leaned into Obama's energy at the rally, as the former commander-in-chief would go on to support the Democratic candidate for governor.

Barack Obama carried Michigan in 2008 and 2012 but Donald Trump was elected president in 2016 and Joe Biden was elected president in 2020.
