NASHVILLE, Tenn. (AP) - Toughening his position, Tennessee Republican Senate Speaker Randy McNally now says embattled GOP House Speaker Glen Casada should resign his leadership post.

McNally told WBIR-TV Friday that he thinks Casada should step aside, though it's the House's decision.

McNally declined to say Thursday whether Casada should resign, then later said Casada would likely be asked to resign if he were a senator.

Republican Gov. Bill Lee also strengthened his criticism of Casada over recently released text messages involving Casada and a former top aide with lewd remarks about women, among other mounting scandals.

Lee said Thursday that, if Casada were in his administration or an executive at Lee's company, he would ask him to resign.

Casada has rebuffed resignation calls and released a plan he says will regain trust.
