Former President Barack Obama spoke at the Democratic National Convention Wednesday night in an impassioned address urging voters not to give up on the democratic process—and imploring them to participate in it.

The 20 minute speech was one of the President's most direct indictments of President Donald Trump's first term in office, with Obama asserting that Trump will never grow to meet the immensity of the office.

Watch below.

Obama said of Trump:

"I did hope, for the sake of our country, that Donald Trump might show some interest in taking the job seriously. That he might come to feel the weight of the office and discover some reverence for the democracy that had been placed in his care. But he never did ... He's shown no interest in putting in the work, no interest in finding common ground, no interest in using the awesome power of his office to help anyone but himself and his friends ... Donald Trump hasn't grown into the job, because he can't, and the consequences of that failure are severe."

Trump only proved Obama right when he began firing off tweets in all-caps, reacting to Obama's speech in real time.

Trump yet again falsely accused Obama of spying on his campaign, and chastised Obama for not endorsing Biden until he was already the presumptive Democratic nominee.

Democratic nominee (and Obama's Vice President) Joe Biden didn't hesitate to point out that Trump only cemented Obama's point.

As Obama's character was on display in the convention, so too was Trump's on Twitter.

They soon began trolling Trump with their reverence for Obama.

Thursday is the final night of the Democratic National Convention, where Obama's former Vice President, Joe Biden, will officially accept the Democratic nomination for President.
