The chairman position is picked from members of the board for a set term, Powells term is ending.
However, Powell, as a middle finger to Trump, isn't leaving the board. Typically after serving as the chairman, a board member would leave the board. Powell, mostly due to Trumps attempt to influence the board, has decided to stay on breaking a 75 year precedent.
Its nice to see someone breaking precedent to stick it to Trump. I just hope he has enough influence to keep Walsh in check, otherwise we're all screwed.
