The former ambassador to Germany pulled his previous endorsement of Robby Starbuck, which both the Starbuck and Ortagus campaigns have confirmed.
"Today I am proud to endorse Morgan Ortagus for Congress. I fought on the front lines with Morgan defending the United States and putting America First. I am grateful for her willingness to once again serve the people," said Grenell.
The announcement arrived as Grenell and Ortagus attended a function together at Mar-a-Lago on Wednesday for Trump-endorsed candidates.
