Chelsea Clinton has been mocked on Twitter after posting a comment made by her four-year-old son Aidan. She claimed that she told him that "it's the 21st day of the 21st year in the 21st century..."
To which the child replied: "Yeah, but it's cooler it's Joe Biden's first full day in the White House."
The post quickly went viral – but a large part of the social media crowd didn't buy it, with many writing sarcastic comments questioning the authenticity of Clinton's story. Some users even found her tweet "preposterous."
The avalanche of replies forced Chelsea to explain herself in a series of tweets.
