"Are you forgetting what you said 2 minutes ago?" Julián Castro asks Joe Biden.

The moderator of the second Democratic debate for 2020 asked the former vice president about his past statements about his own plans for a presidential bid. Joe Biden responded with a grin and said, "I'm not announcing, I'm not announcing". Julián Castro's reaction was instant. "Are you forgetting what you said two minutes ago?" he quipped.
Joe Biden has been on the political stage for a long time. And the Julián Castro to Joe Biden meme is just one of many examples of his propensity for forgetting what he just said.
After Julián Castro, former Secretary of Housing and Urban Development, questioned Joe Biden's memory on Thursday night during the second Democratic presidential debate, Biden responded by calling Castro "a bright man" but "not bright enough."
