Those with access to President Joe Biden behind closed doors say that his condition is deteriorating at an accelerated rate as he continues to face growing calls to step aside as the party’s presidential nominee this fall following his disastrous debate performance last week, according to reports.

The New York Times reported that those closest to Biden have noticed that he “increasingly appeared confused or listless, or would lose the thread of conversations” and that these incidents are “growing more frequent, more pronounced and more worrisome.”

Biden was so worn out from trips to Europe prior to last week’s debate that he had to be “given time for an afternoon nap each day” during his week-long debate prep — in which he never started work earlier than 11 a.m. — in order to recharge his batteries.

The report highlighted numerous incidents that happened while he was in Europe that turned into viral videos on social media, including embarrassing moments at the D-Day anniversary ceremony in France and his subsequent trip to Italy for the G7 Summit.

The White House is refusing to let Kevin C. O’Connor, the White House physician, answer questions from the media about Biden’s condition and said that O’Connor does not believe that Biden needs to be re-evaluated for Parkinson’s disease — even though the condition that most speculate Biden has is some form of dementia. The administration went even further and denied that Biden had ever taken “Levodopa or other drugs for that condition.”

Presidential historian Douglas Brinkley said that it was visibly obvious that “there’s been a slowdown in the past two years” for Biden and that the administration is trying hard to only show “the Biden they want us to see.”

The report noted that Biden has granted fewer interviews than any president in modern history and has held fewer press conferences than any president in over 40 years.

During his visit to Europe, a senior European official told the Times that everyone was “shocked” by Biden’s cognitive decline and that he appeared “out of it” a lot of the time. European leaders reportedly could not stop talking about Biden’s condition and took steps to avoid embarrassing him by either walking too fast or letting him wander off.

The Financial Times reported this week that European officials were outright terrified over Biden’s shape as they worried about whether he had the juice to finish the presidential race.

The report highlighted public comments from numerous officials who said that Democrats needed to replace Biden before it was too late.

As Biden appears to be circling the drain, his inner circle is tightening its grip on power and shielding him even more from public view in an effort to protect him from making further mistakes.

NBC News reported on Tuesday that Biden’s son, convicted felon and drug addict Hunter Biden, was now attending official White House meetings with the president to the shock of most in the administration.
