The campaign took notice, and in September 2016 she was officially hired as a senior adviser. In an interview with Yahoo News, Miller—who was then serving as the campaign’s senior communications director—spoke glowingly of Delgado as a “triple threat” with ample “conservative street cred.” “The thing I love about A.J.,” he said, “is the range of audiences she can go and speak to.”

Delgado was assigned to work in the campaign’s press operation, coordinating outreach to Spanish-language media and appearing on national television to speak on the candidate’s behalf. She split her time between Miami and Manhattan, spending several days a week in Trump Tower. This is where she says her relationship with Miller began—working side by side to promote Trump’s message.

The two began dating in mid-October, Delgado said, adding that while she knew Miller was married, he told her at the time that he was separated from his wife. “Among other things, I was really drawn to his talent,” she told me. “He is the best at what he does.”

(Miller declined to discuss the details of his relationship with Delgado and their son, and responded to a series of questions with a statement from his attorney.)

Their relationship, as described by Delgado, was a far cry from the torrid fling that’s been recounted in gossip columns. She showed me text messages in which the two appear to be making dinner plans, affectionately calling each other “babe” and “bae,” and casually discussing how to leave the office together without provoking suspicion among colleagues.

After Trump’s surprise victory in November, Delgado and Miller both joined the transition team, where she says their relationship continued. But just a couple of weeks after Election Day, Delgado discovered she was pregnant. She held off at first on sharing the news, unsure of how Miller would take it.

“I finally told him one night when we were in bed and I couldn’t fall asleep,” she said.

Miller reacted calmly, Delgado recalled, but came back with some complicating news of his own. “Well this is going to be extra awkward for me to handle,” she remembers him saying, “because my wife is expecting.”

Not comprehending at first, Delgado replied, “Expecting what?”

“Obviously that floored me,” she told me. “It was a very rough thing to hear.”

Some women would have considered abortion. And according to Delgado, Miller asked her on two separate occasions if “there was any chance I’d terminate the pregnancy.” (Miller denied this.) But she told me she didn’t seriously entertain the notion. “The minute I knew I was pregnant, I knew I wanted him,” said Delgado. “I can’t explain it. This was somebody I wanted to meet, and wanted to have in my life. It was God telling me, ‘Hey, you should be a mom and I’m sending you this amazingly wonderful gift, so take it.’ There’s no way I was just going to say no thanks to God.”
