Michell Cantwell announced her resignation from Leander City Council Aug. 27 in order to run for Williamson County treasurer.

Cantwell said in a statement she will vacate her seat on City Council when a replacement has been elected. State and city "resign to run" laws dictate an office holder cannot hold one position while running for county treasurer, commissioner, judge or other seats.

"I will continue to serve on the Leander City Council until an election determines a replacement for the remainder of my term," Cantwell said. "I sincerely appreciate the support and confidence the Leander voters have extended to me in representing their interests here."

The primary election for Williamson county treasurer will be held March 4, 2014. Cantwell faces Republican Jerri Jones, who announced her candidacy in spring 2013.
