Donald Trump's first campaign manager appeared pleased Friday morning to learn that the GOP nominee's second campaign manager, Paul Manafort, had just resigned.

"I will never get tired of winning," Corey Lewandowski said in an interview on CNN.

It is no secret that Lewandowski, who was fired from the Trump campaign in June, and Paul Manafort did not get along when the two worked together on the Republican candidate's campaign.

Their relationship was so dysfunctional, that Lewandowski's eventual firing from the campaign reportedly came after he lost a power struggle with Manafort.

So when it was announced Friday morning that Manafort had resigned, making way for the Trump team's latest additions, GOP pollster Kellyanne Conway and Breitbart chief Stephen Bannon, Lewandowski, who has been passive aggressively sniping at Manafort for weeks, took a minor victory lap in an interview on CNN.

The moment occurred as the network's Kate Bolduan asked Lewandowski about a seemingly celebratory note he re-tweeted Friday morning that read, "Lewandowski is winning so much even he may get tired of winning."

"There's no secret that there's no love lost between you and Paul Manafort. Anyone who has covered the campaign knows that. What did you mean by that re-tweet?" she asked.

"One of the things we had talked about many times in the campaign, and Donald Trump has said this, 'You're going to be tired of winning.' And I can tell you that I will never get tired of winning," Lewandowski said. "I thought it was pretty appropriate, because as we continued to win –"

Bolduan interjected, "How did you win on this one, Corey?"

"I didn't win, but I thought it was funny. Because you know what is — is people think I won. I had nothing to do with this. This was about Donald Trump. He's running for president. This is about what is best for Donald Trump, what is best for the American people and what is best to lay out his case that Hillary Clinton is not prepared to be the President of the United States," the ex-campaign manager said.

Trump explained in a statement Friday morning that Manafort had left the campaign.

"This morning Paul Manafort offered, and I accepted, his resignation from the campaign," Trump said in a statement. "I am very appreciative for his great work in helping to get us where we are today, and in particular his work guiding us through the delegate and convention process."
