GOP to White House: End summit mystery
Trump nominates Callista Gingrich for ambassador to the Vatican
The nomination comes just five days before Trump is set to meet with Pope Francis at the Vatican during his first trip abroad as president.
The nomination follows months of speculation and vetting that at one point, according to a New York Times report, nearly drove Gingrich to withdraw herself from consideration.
Gingrich is a member of the choir at the Basilica of the National Shrine of the Immaculate Conception in Washington, D.C., and is said to have been a key factor in her husband's conversion to Catholicism.
Her husband was a vocal supporter of Trump during his presidential campaign and has continued to defend him since he took office in January.
