"When I return to town on June 3, I will meet with caucus leadership to determine the best date for me to resign as speaker so that I can help facilitate a smooth transition," Casada said in a statement.
Casada announced the decision just a day after previously shrugging off a 45-24 secret ballot vote from his GOP caucus determining they no longer had confidence in his ability to lead the Tennessee House. Shortly after the hours long decision, Casada said he would work "months" to regain trust from his colleagues.
However, the promise wasn't enough to satisfy critics and instead an increasing number of Republican leaders began demanding he step aside, including a stern warning from Tennessee Gov. Bill Lee saying he would call a special legislative session if Casada didn't voluntarily give up the key spot.
Casada has been dogged by calls to resign since it was revealed he exchanged text messages containing sexually explicit language about women with his former chief of staff several years ago, among other controversies.
Casada took office in January. He received 47 secret ballot votes out of 73 Republicans in the 99-member chamber to become speaker-elect in November. Then the majority leader, he defeated Reps. Curtis Johnson of Clarksville and David Hawk of Greeneville.
