House Minority Leader Nancy Pelosi (D-Calif.) admitted something over the weekend that she never believed she would say.

The House Democratic leader made the admission Sunday during an appearance on ABC News' "This Week" when she accidentally referred to President Donald Trump as "President Bush" during a discussion with show host Jonathan Karl about Trump's first 100 days as president.

Karl had just asked Pelosi how, if Democrats re-take the House in next year's mid-term election, Democrats would work with Trump's White House, which is fundamentally at odds with the Democratic agenda. Karl said Pelosi and the Democrats appear to be the "party of no" as of late, but Pelosi disagreed.

"I see everything as an opportunity. And I've never have seen so much willingness to help win. And winning means winning for the American people, that either we win or whoever wins understands the priorities of the American people," Pelosi said.

That's when Pelosi began to say the priorities of Trump aren't the priorities of the American people. Instead, she accidentally said "President Bush," referring to former President George W. Bush, who she worked with as Speaker of the House in 2007 and 2008.

"And they are not the President Bush—" Pelosi said.

Realizing her verbal error, Pelosi put her hand over her heart and exclaimed: "I’m so sorry, President Bush! I never thought I’d pray for the day that you were president again!"

Then Pelosi clarified her comments.

"And so you asked the question, how would I work with a Republican president? The way we worked with President Bush," she said. "We got great deal accomplished."

However, Sunday's error wasn't the first time Pelosi became confused and referred to Trump as Bush. During a news conference in early February, just two weeks into Trump's presidency, she also called Trump "President Bush."

"While its only been a couple of weeks since the inauguration, we've seen nothing that I can work with President Bush on," she said at the time.
