Sanders tweeted Tuesday evening that she was excited to welcome Gidley to the West Wing press shop.
Gidley's appointment was first reported by Fox News and later confirmed by Sanders.
This will be a reunion of sorts for Sanders and Gidley, who worked together on campaigns for the press secretary's father, former Arkansas governor Mike Huckabee. Gidley served as a communications strategist on two presidential campaigns, Huckabee's in 2016 and former senator Rick Santorum's (Penn.) in 2012, logging tens of thousands of miles with both candidates.
Based most recently in South Carolina, Gidley has years of experience in conservative politics, personal relationships with Washington reporters and experience as a political analyst on cable television news.
