Chris McDaniel (R) is expected to announce later this week that he will wage a 2018 primary challenge against Sen. Roger Wicker (R-MS), Politico reports.
“McDaniel’s plans have been the subject of speculation for months. With the 80-year-old Sen. Thad Cochran’s (R-MS) health in decline, many believed that McDaniel would run for the seat should it become vacant.”
