Joe Biden has announced that Ron Klain will be the White House chief of staff in his administration. Klain worked for Biden when he was a senator in Delaware and also as Biden’s chief of staff when he was Vice President. Klain is given a lot of credit for helping the Obama administration get out of the ’08 recession as well as combating the Ebola outbreak. Given Klain’s long history with Biden and his expertise in public health and economics, it’s no surprise he’s joining Biden’s cabinet.
