Callista Gingrich, the wife of Newt Gingrich, the former House speaker and a friend of Mr. Trump’s, is in the running to be ambassador to the Holy See, according to a person briefed on the discussions.
Mr. Gingrich, reached by telephone, said that he was aware that his wife had been on a list for the job, but declined to say where things stood. The former speaker took himself out of the running for a cabinet post after it became clear that Mr. Trump was looking elsewhere for a secretary of state.
Mr. Trump has known Newt and Callista Gingrich socially for years. They’re members of his golf club in Virginia, and have been at his club, Mar-a-Lago, in Palm Beach, Fla. Mr. Gingrich was one of the people Mr. Trump consulted in 2015 when he had already determined he would run for president.
