“‘Donald Trump likes to claim he built this economy,’ Obama said. ‘But I just want to remind you that America created 1.5 million more jobs in the last three years of the Obama-Biden administration than in the first three years of the Trump administration. That’s a fact; look it up. And that was before Trump could blame the pandemic. He, in fact, inherited the longest streak of job growth in American history, but just like everything else he inherited, he screwed it up.’

...Obama’s numbers on both claims check out. More than 8 million jobs were created from 2014 to 2016, vs. more than 6.5 million from 2017 to 2019.”
