Putin rips speculation that Biden has dementia saying president ‘is fully in the know’ & ‘never misses a single detail’

VLADIMIR Putin has dismissed baseless speculation that Joe Biden has dementia as he said he was "in the know" and "never missed a detail" at their summit in Geneva.

The Russian leader's comments come as 14 Republicans urged Biden to take a cognitive test as they claim he is unfit to be president.

Putin rubbished suggestions that the Democrat “performed poorly” at the event, Russian news agency TASS reports.

He said: "Biden is a professional and one should work very attentively with him to avoid missing any detail. I can say with certainty that he never misses a detail."

Putin said Biden was "in the know" at the meeting despite reports that the Democrat was spotted with a cheat sheet.

The Russian strongman said: "He is fully in the know. He looked into his notes from time to time but we are all doing this."

Putin was not as complimentary towards White House press secretary Jen Psaki, The New York Post reports.

He said: "His press secretary is young, educated and [a] pretty woman. She is mixing things up all of the time. This is not because she is not enough educated or has a bad memory (sic)."

Hitting back, a White House official responded: "It is a Russian propaganda cliché to attempt to discredit effective messengers who concern them with gendered and baseless criticism."

Biden has received a barrage of criticism following the summit in Geneva.

Ronny Jackson, Donald Trump’s former White House doctor, claims Biden is not “physically or cognitively fit to be president”.

He told Sean Hannity: “We can’t sit on this any longer. He’s not physically or cognitively fit to be our president right now.”

The former White House physician said he is aware of the demands of the presidency but said the Democrat is not “inspiring confidence” on the global stage.

Jackson told The Hill: "Just everything that has been going on for the last year and a half … [Biden] doesn't know what's going on, where he's at. He's very confused all the time.

"They deserve to know that he or she can perform the duties demanded of the office, and they deserve to have full transparency on the mental state of their highest elected leader."

Lara Trump slammed Biden for only answering questions from a pre-approved list of journalists after the talks in Switzerland - adding it makes the US look "ridiculous".

And, former Navy Seal commander David Sears claimed Biden "failed" Putin's test when F-22 planes faced off against the Russian navy off the coast of Hawaii earlier this week.

The Russian exercise included surface ships, anti-submarine aircraft, and long-range bombers.

The US sent the fighter jets to respond to the bomber flights, but the bombers didn't enter the Air Defense Identification Zone and were not intercepted.

Sears told Fox: “It’s obviously a test and President Biden failed.”

Biden said the meeting was constructive and talks didn't take place in a "hyperbolic atmosphere".

He told reporters that he didn't make any threats towards Moscow but warned of "consequences" if Kremlin critic and opposition leader Alexei Navalny dies in prison.

But, Trump, who was accused of "cozying" up to Putin during his presidency, said the summit was a "good day for Russia".
