When he was elected in January, House Speaker Glen Casada was poised to become one of the most powerful figures in the state. But less than five months later, he’s agreed to resign.

Casada’s tumble from grace unfolded in less than three weeks. Here are some key moments:

Another screenshot suggests that Cothren may have doctored evidence regarding charges against an African American activist, Justin Jones. Cothren denies doing so.

May 6: Cothren admits to using cocaine in his state office in recent years. Then, The Tennessean publishes leaked text messages showing the aide making sexual advances to interns and a lobbyist between 2014 and 2016.

May 9: NewsChannel5, citing anonymous sources, reports the FBI is investigating whether lawmakers were offered improper incentives in exchange for voting for school vouchers, an issue that Casada championed. Gov. Bill Lee tells The Tennessean that if Casada worked for his administration, he would ask him to resign.

May 10: The Black Caucus holds a press conference to say Casada never reached out to them about diversity training.
