BREAKING: Kamala Harris unfollows Joe Biden on Twitter as VP announcement approaches

Kamala Harris is thought to be one of the frontrunners in the race to become Joe Biden's Vice-Presidential candidate. The unfollowing of Biden might be considered a sign that he is leaning in another direction.

Some online have suggested that Harris had never followed Biden. Others suggested it might be a Twitter glitch.

TPM contributor Kyle Kashuv tweeted, "It’s real. But it also might have the opposite meaning of what we think. Not sure, might be an ethics violation. So her official senate account had to unfollow the political campaign account."

In addition to Harris, Obama-era United States Ambassador to the United Nations Susan Rice is also considered to be a favourite to be Joe Biden's running mate.

Other candidates include Karen Bass, Stacey Abrams, Val Demings, and Atlanta Mayor Keisha Lance Bottoms.
