Berkeley County Republican Party Chairman Josh Whitley said Tuesday he will run for the county council seat being vacated by Tim Callanan.
Callanan stepped down from the District 2 seat at noon Tuesday to become the county's deputy supervisor for finance.
District 2 includes Daniel Island, the Clements Ferry corridor, and portions of Hanahan and Goose Creek.
Whitley, 31, grew up in Berkeley County and now lives on Daniel Island, where he also practices law.
He made the announcement in his law office, flanked by several county officials and statehouse members. He said he has endorsements from 26 politicians.
"I cannot begin to tell you how humbled I am to have the support of so many elected officials," he said.
A conservative, Whitley said he will focus on lowering taxes and improving infrastructure.
Whitley has established himself as a watchdog of county politics. In 2012, he led a charge against the school district's Yes 4 Schools campaign and eventually took his concerns to the state Attorney General's Office, which led to an investigation and two indictments for the district's communications director.
He said he will not have to give up his post with the Republican Party, which he has held since June, unless he has a Republican challenger.
County Council members are paid $12,000 per year.
