US President Joe Biden has been ruthlessly mocked online after reading the instructions on his teleprompter on Wednesday.

Users on X roasted the oldestever sitting president following another gaffe by Biden.

“Besides the truth, it seems Joe Biden’s worst enemies are the teleprompter and a set of stairs,” wrote one user.

President Biden hosted a speech at a trade union conference in Washington DC as he continues his reelection campaign.

Biden’s appearance at the union conference came after he was endorsed by the North American Building Trades Unions (NABTU).
