His step back into the political arena offered a preview of his message for the fall's midterms.
In August, Mr Obama endorsed 81 Democratic contenders in 14 states, emphasising young, diverse candidates running for state-level offices in an attempt to help new party leaders establish themselves.
Since leaving office in January 2017, Obama has largely refrained from directly criticizing Trump or his administration. Obama is likely to be less helpful in some of the most competitive Senate races playing out in states Trump won. He adds, "I found he's very good for sleeping". And on Twitter, Wilson used Obama's speech not as a chance to attack Obama, but to have a laugh at Trump's expense.
"We're going to take a look at what he had, what he gave, what he's talking about also where he is right now", Trump reporters on Air Force One on his way to a North Dakota campaign clambake.
"He is acutely aware that he has a mixed record of success when his name is not on the ballot", said one person familiar with President Obama's thinking, who asked not to be named discussing internal deliberations.

Barack Obama delivered a very passionate speech meant to remind the citizens that they need to defend and protect Democracy and that voting is a big part of what they can actively do to achieve that.
He criticized the divisive politics of the Trump era and took aim at recent Republican policy moves such as the $1.5 trillion in tax cuts that ballooned the nation's budget deficit. That's how real change starts, Obama said. Obama, according to Schlapp, "spent billions of dollars in stimulus money while creating a stagnant economy".
To avoid such traps, Obama in his post-presidency has chosen his spots carefully, opting to do targeted robo-calls past year to support Democratic Sen. "We are Americans. We're supposed to stand up to bullies, not follow them", he said to applause. He attempted to connect Trump's views with the members of the Republican Party as a whole, particularly on Russian Federation, and noted how far the GOP had seemed to stray from its roots.
Obama also jabbed Trump on the issue the current president frequently heralds as one of his greatest achievements: The strong economy.
