A former White House stenographer warned that Joe Biden’s public speaking ability has significantly deteriorated since he left the vice presidency four years ago. He said the change in his mental state is such that he’s “not the same Joe Biden.”

Mike McCormick worked as a White House stenographer for 15 years. Specifically, from 2011 to 2017, he covered the speeches of Barack Obama’s then-vice-president.

He recently published his book, “Joe Biden Unauthorized.” He recounts his experience working with Biden and takes a critical look at the former vice president’s current state.

“It is a complete difference from what he was in 2017,” McCormick said in an interview with the Washington Free Beacon released on Sept. 8.

“He’s lost a step and he doesn’t seem to have the same mental acuity as he did four years ago,” he added. Speaking to the political website, he said Biden “doesn’t have the energy, he doesn’t have the pace of his speaking.” “He’s a different guy,” he said.

During his work at the White House, McCormick regularly traveled with Biden to transcribe his speeches, public talks with foreign leaders, and off-the-record media briefings.

He said that, contrary to current perceptions, Biden had a talent for connecting with the public and often improvised outside of his prewritten speeches.

“He read that [Democratic National Committee speech] verbatim … it’s not Joe Biden anymore,” McCormick said.

If Barack Obama’s former vice president beats Republican Donald Trump in November, he will be sworn in at 78 (he will be 80 before he reaches the midpoint of his eventual first term).

But beyond age, what has caught the eye during the election campaign is his cognitive health.

In a series of appearances, for example, Biden seemed to have lost his train of thought, “‘struggled’ to finish a sentence” or forgotten where he was.

Likewise, McCormick said the former vice president now also seems to “get lost” during interviews. In fact, in answering questions asked by the press recently, Biden appeared to have read the answers directly from a teleprompter, including instructions from his staff, such as “END OF APPOINTMENT” and “TOPLINE MESSAGE.”

He has also made some strange statements: in a dialogue with the online audience, he said that when he was a patient at Walter Reed Hospital, the nurses “breathe in my nostrils to make me move.”

Many other public appearances have raised the alarm about his cognitive abilities. In February, he said he was running for the Senate. During the Democratic nomination race, he told people to “visit” Joe’s 30330 text message (mistaking it for a website). He also advised parents to make sure they play “the record player at night” to help their children. In March, he began reciting the Declaration of Independence and immediately forgot it, and during a speech, he mistook his wife, for his sister.

As part of the campaign, President Trump has dubbed him “Sleepy Joe,” and the Trump campaign released a video ad last month, suggesting that the Democratic candidate is suffering from cognitive decline.

“Joe Biden is clearly incapable of functioning as president,” former Republican representative Newt Gingrich said, explaining that “every time he comes out from hiding in the basement, it is embarrassingly clear that he could not possibly negotiate” with foreign leaders such as Chinese dictator Xi Jinping or Russian President Vladimir Putin.

“He is performing weaker and weaker with each passing week. Even when his campaign can control every aspect of his events or appearances, there is something pathetic about Biden’s inability to project strength or articulate any firm ideas,” Gingrich summarized in a mid-August column on Fox News.

According to a poll conducted in late June by Rasmussen Reports, nearly four in 10 voters believe Biden has dementia.
