In a burst of activity this week, the enigmatic first lady told Americans what she has been up to after a quiet summer. Her activities have included filming a new documentary series about her life. Melania Trump spoke at her “Fostering the Future” event at the White House in August.

After a summer spent out of the public eye, the first lady popped up in New York City this week with a few autumnal announcements. In an interview with “Fox & Friends” released on Wednesday morning, she said that she will be answering “private questions” in a two-part documentary series set for release later this year. She has planned the state dinner for Xi Jinping, the president of China, scheduled for Thursday. She is counting on the Senate to pass legislation that will expand federal benefits to children in foster care.

“You don’t see me everywhere,” Mrs. Trump told a docile panel of cable-news interviewers. “But behind the scene, I’m working nonstop.” Later, she appeared on “The Big Money Show” and declared that she was too busy to read books or binge-watch TV. She said she reads executive orders. “The other day, somebody asked me ‘what book you reading?’” Mrs. Trump said. “I said ‘executive order.’”

On Tuesday, Mrs. Trump was at her husband’s side as he began his rounds. President Trump kicked off his time at the United Nations General Assembly by berating a CNN reporter. Mrs. Trump kept to her own schedule, holding a luncheon dedicated to her child-focused initiatives. She announced that private companies including Amazon, Zoom and Google had pledged to expand technological tools for children across the world.
