President Barack Obama said goodbye to the nation Tuesday night, during an emotional farewell address. He spoke of his presidency, touching on both the higher and lower points, and remained hopeful of the future of the nation.

He also warned that “we as a nation must continue to work to protect the values that America was built upon. Democracy can buckle, when we give in to fear,” he said. “So just as we, as citizens, must remain vigilant against external aggression, we must guard against a weakening of the values that make us who we are.”

The crowd of supporters viewing the address often interrupted the speech with chants of “I Love You, Obama!” and “four more years!”

President Obama recognized his successor Donald Trump, saying he was committed to a peaceful transition of power. But he warned that going forward Democrats shouldn’t (blindly) fall in line with their commander-in-chief.

He also touched on the hightened tension of race relaations under his presidency and demanded that our differences be identified and reconciled and that for real chnge, “hearts must change.”

The president got especially emotional during his shout out to First Lady Michelle Obama, saying, “You took on a role you didn’t ask for and made it your own with grace and grit and style and good humor,” he said. “You made the White House a place that belongs to everybody.”
