"The Daily Show with Jon Stewart" has become one of the most influential programs on television by offering honest, passionate analysis and satirical commentary of the news. Politicians, network executives, and everyday Americans tune in four times a week and esteem his segments for their thoughtful monologues, sharp correspondents, and well-timed celebrity guests.

Since 1999, Jon Stewart has tackled current events and changed the way we talk about the world around us. His episodes show incredible range of emotion — from hilariously referring to President Obama as “dude,” to his powerful, solemn monologue after the shooting in Charleston.

Tonight, Stewart will give his last performance on "The Daily Show." He and President Obama have shared the screen a total of seven times over the past 10 years, discussing the President's work as a Senator, on campaigns, and in the White House. Most recently, President Obama sat down with Stewart last month as part of the trailblazing final season.

Here are four of our favorite moments Jon Stewart has shared with President Obama over the years:

The right to vote is one of the most fundamental rights of any democracy.

Fifty years ago today, because of the sacrifice of countless men and women, that right was secured for more Americans.

On August 6, 1965, President Lyndon Johnson signed the Voting Rights Act into law — breaking down legal barriers at the state and local level that had prevented African Americans and others from exercising their constitutional right to vote.

Because of that law — one of our nation's most influential pieces of legislation — Americans who were previously disenfranchised and left out of the democratic process were finally able to cast a ballot. The law was designed to ensure that all American citizens, regardless of the color of their skin, had an equal opportunity to make their voices heard.

But that law didn’t come to pass because folks suddenly decided it was the right thing to do.

This past March, I had the honor of traveling to Selma, Alabama for the 50th anniversary of the “Bloody Sunday” march from Selma to Montgomery. Those who marched over the course of those five days in 1965 were fighting to ensure that African Americans could exercise their right to vote under the 15th Amendment of our Constitution. They were marching in the face of a segregationist system that wanted to deny them that right. 

And on one afternoon, two visions of America met on the Edmund Pettus Bridge. Those nonviolent marchers, representing the idea that all men and women are created equal and deserved to be treated as such, stared into the faces of those who represented a South that stood for the racial segregation and oppression of Jim Crow.

Roughly 600 people stood on the right side of history that day — armed only with their faith, and the conviction that we could be better. They were willing to sacrifice their own bodies in order to help bring America closer to its ideals of equality and justice for all.

Yesterday, President Obama spoke on the Iran deal at American University's School of International Service.

In 1963, President John F. Kennedy also delivered a historic foreign policy speech at American University. Just eight months after the Cuban Missile Crisis, President Kennedy had boldly entered into a diplomatic agreement with an adversary of the United States -- the Soviet Union. He faced criticism at home for choosing to pursue a peaceful weapons agreement with a country no one trusted.

President Kennedy addresses the American University Commencement, recieves honorary degree. 

 

President Kennedy's diplomatic approach succeeded in advancing the national security interests of the United States -- and the Iran deal does the same. 

 

50 years ago, JFK spoke of peace in a nuclear age at @AmericanU. Today, @POTUS will too. Read JFK's speech: http://t.co/Vk6SI5hkiF #IranDeal

Both Presidents believed that a peaceful agreement was preferable to alternatives which would likely lead to military confrontation.
