Don Lemon didn't hold back when he dragged Donald Trump on Sunday.

The CNN anchor, who is apparently tired of hearing the sitting president continue to place blame on Barack Obama, stared into the camera with an exhausted expression and pondered aloud the factors that may be contributing to Trump's never-ending grudge against the 44th president. 

“What is it about President Obama that really gets under your skin? Is it because he’s smarter than you?" Lemon said. "Better educated? Made it on his own — didn’t need Daddy’s help?"

And the punches kept coming.

"Wife is more accomplished? Better looking?" the CNN anchor said. "I don’t know, what is it, what is it about him? That he’s a Black man that’s accomplished being president? That he punked you on the whole birth certificate thing? What is it about him? Just wondering.”

Lemon's rant came after Trump tried to dig into another conspiracy theory involving Obama. The president retweeted an article from a conservative blogger, saying that Obama was behind the investigation into Russia's role in Trump's victory in the 2016 election, according to Daily Mail. 

The CNN host described Trump's latest conspiracy theory as "a new low for a president who goes low all the time."

"It's obviously completely untrue," he said. "It's a disturbed fantasy. Obviously he doesn't expect you to believe it. He just wants to turn the page to get you to think about something, anything other than one of the worst crises in this nation's history."

Lemon then suggested for the president to look in the mirror.

"It's you," he said. "This is nothing but a shameless attempt to distract from your own administration's mishandling of a crisis that has cost over 67,000 American lives."

Obama wasn't the only punching bag for Trump on Sunday. It was also former President George W. Bush who felt the wrath after he released a video in which he reminded Americans to remember "how small our differences are in the face of this shared threat." 

"In the final analysis, we are not partisan combatants. We are human beings, equally vulnerable and equally wonderful in the sight of God," Bush said. "We rise or fall together, and we are determined to rise."

That's when the current president retreated to Twitter to unleash his fury with a message which, naturally, included a spelling error.

"He was nowhere to be found in speaking up against the greatest Hoax in American history!" Trump said. 

Lemon also defended the 43rd president.

"Thank goodness there is a real president that is showing compassion for his fellow Americans. And it's not President Trump," he said. "It's former President George W. Bush with a message full of images of and concern for all Americans."

Last week, Trump bashed Lemon, calling him the "dumbest man on television."

“I must admit that Lyin’ Brian Williams is, while dumber than hell, quite a bit smarter than Fake News @CNN 'anchorman' Don Lemon, the ‘dumbest man on television,’” Trump tweeted. “Then you have Psycho Joe ‘What Ever Happened To Your Girlfriend?’ Scarborough, another of the low I.Q. individuals!”

Lemon also included a message from Obama during his segment.

"These aren't normal times as we all manage our way through a pandemic unlike anything we've seen in a century," Obama said during his video endorsement of Joe Biden last month. "If you lost somebody to this virus or if someone in your life is sick or if you're one of the millions suffering economic hardship, please know that you are in our prayers."  

Well, would you look at that: leadership.
