After US President Joe Biden announced his candidacy for re-election in 2024, the Deputy Chairman of the Security Council of the Russian Federation Dmitry Medvedev, suggested, on Tuesday, that the US military better take precautionary measures to avert irreparable damage in the event the "desperate grandpa" gets re-elected.

On his Telegram channel, Medvedev wrote: "Biden has taken his decision. A desperate grandpa." He explained: "If I was in the place of the US military I would quickly produce a fake briefcase with fake nuclear codes in case he wins so as to avoid irreparable consequences."

Earlier in the day Biden confirmed that he will seek a second term at the White House in 2024 through a video made by his campaign team, which opens with scenes from the January 6 attack on the US Capitol by supporters of former President Donald Trump.

The 80-year-old and oldest US President ever said, "When I ran for president four years ago, I said we're in a battle for the soul of America, and we still are," adding, "This is not a time to be complacent. That's why I'm running for re-election."

"Let's finish this job. I know we can," he added. VP Kamala Harris has also announced today that she will be running for VP again next year alongside Biden.

He further illustrated Republican policies as threats to American freedom and promised to fight for women's healthcare and limit the cut of Social Security and banning of books, while blasting "MAGA extremists."
