Fox News host falsely tells Trump a Biden Cabinet official just resigned, only to correct the record after he called it a 'big victory'

• A Fox News host erroneously said on-air that DHS Secretary Alejandro Mayorkas had resigned.
• Harris Faulkner broke the news to former President Donald Trump on a call-in interview Monday.
• Trump called the non-development a "big victory," prompting Faulkner to correct the record.

During a call-in interview with former President Donald Trump on Monday, Fox News host Harris Faulkner falsely reported that Department of Homeland Security Secretary Alejandro Mayorkas had just resigned.

"I want to double check this with our producers," Faulkner said with Trump on the line. "Um, the DHS Secretary Alejandro Mayorkas has resigned, Mr. President."

"Well, I'm not surprised," Trump replied. "Good. That's a big victory for our country."

As the former president reveled in the non-development, Faulkner pressed her finger to her earpiece and interjected.

"Hold on, let me, let me stop, let me stop. Let me listen to my team one more time, forgive me," Faulkner said. "Forgive me, that has not happened, and I apologize."

Faulkner was asking Trump about the unfolding situation involving thousands of unaccompanied migrant children at the US-Mexico border.

Mayorkas has blamed the Trump administration for causing the problem, particularly for dismantling the program that children used to apply for asylum from their home countries.

"OK, cross off that victory," Trump said before Faulkner moved on.

Speaking of his desire for Mayorkas to resign, Trump added: "Well I think that'll eventually happen, he's [in] way over his head."

Faulkner referenced a statement Trump released on Sunday night, decrying what the former president described as Mayorkas's "pathetic, clueless performance" on the Sunday shows.

"I want to tell everybody you issued a statement last night and ... you're just talking about him, just to clarify, as somebody who you feel is not competent to, to handle what's going on. So let me clean up on aisle seven with my error," Faulkner added. "He has not resigned."

Fox News later told Insider in a statement that "the error stemmed from an audio issue in a virtual working environment. We corrected the mistake and continued on with the interview."
