Just to play devil's advocate here, Biden isn't the first president to need a little help. By all accounts, Obama was not at all a good speaker without the teleprompter. Ronald Reagan often had to ask aides whether to sign or veto a bill because he honestly couldn't make up his mind. And of course, very few Presidential speeches are actually written by the President.
'YOU will sit': Biden is caught with cheat sheet at G20 informing him when to sit, speak and take a photoPresident Joe Biden accidentally revealed a list of instructions telling him when to take photos and speak while at the G20 Summit in Indonesia.The notes told the president where he should sit and the proper time to do so - along with multiple reminders that his opening remarks were on the next page. It is not the first time Biden has been caught with cheat sheet while in important meetings.
Being President is a complicated job and I would imagine that they all receive scripts of when and what to do, especially when meeting with other governments. Grampa Joe probably has to read it more than others, given that his hand is on the doorknob of 80.
