Did Biden step down

I can understand why you might think that Biden has stepped down. There have been a lot of rumors and misinformation circulating online.
But I can assure you that Biden has not stepped down. He is still the President of the United States.
I know that there are a lot of people who are unhappy with Biden. They don't like his policies or they don't think he's doing a good job. But that doesn't mean that he has stepped down or that he should step down.
The President of the United States is elected to a four-year term. Biden was elected in 2020, so he will not be up for re-election until 2024.
Of course, anything can happen in politics. But there is no evidence to suggest that Biden is planning to step down before the end of his term.
So, to answer your question, no, Biden has not stepped down. He is still the President of the United States.
Let's just all take a deep breath and relax – Biden's still in charge.
