One month into his presidency, President Donald Trump is still looking for someone to fill the vacancy as his National Security Adviser.
This is because Michael Flynn resigned earlier this week.
Trump has since offered the position to retired Vice Admiral Robert Harward, who declined.
There are a few other names being considered.
President Trump will speak with at least four candidates to serve as his next national security adviser on Sunday, including a new name on the shortlist: West Point superintendent Lt. Gen. Robert Caslen.
Trump currently has meetings scheduled with retired Lt. Gen. Keith Kellogg, who has been acting as the national security adviser since Mike Flynn resigned Monday, as well as Lt. Gen. H.R. McMaster, former United Nations ambassador John Bolton and now Caslen, according to a press pool report.
