The White House deputy chief of staff and his wife welcomed their youngest son on June 3, 2026, with Katie publicly announcing the birth on June 10. She shared family photographs featuring their newborn and three older children, giving followers a rare glimpse into their growing household.

Stephen Miller and Katie Miller are parents to four children: Mackenzie Jay, Jackson Grant, Hudson Monroe and Hawthorne Hayes Miller. The couple, who married in February 2020, now have one daughter and three sons. Their newest arrival comes during a demanding period for both parents, with Stephen holding a senior position in President Donald Trump’s administration and Katie pursuing her career as a conservative podcast host.

How Many Children Does Stephen Miller Have?

Stephen Miller has four children with his wife, Katie Miller, formerly Katie Waldman. Their eldest child, Mackenzie, was born in November 2020, followed by Jackson in February 2022, Hudson in September 2023 and Hawthorne in June 2026.

All four children were aged five or younger when Katie announced the birth of their youngest son.

The couple have occasionally shared photographs of their children on social media, particularly during holidays, birthdays and major family celebrations.

However, they generally keep details about their children’s daily routines, education and personal lives away from public attention.

Their family has grown steadily since their wedding, with each new arrival marking another important milestone in their marriage.

Mackenzie Jay Miller

Mackenzie Jay Miller was born in November 2020 and is Stephen and Katie Miller’s eldest child and only daughter.

She arrived approximately nine months after her parents married, beginning their journey into parenthood.

Mackenzie turned five in November 2025 and is approaching her sixth birthday.

As the eldest of four siblings, she has appeared in several family photographs shared by Katie, including images celebrating the arrival of her youngest brother.

Although her parents work in highly visible political and media roles, relatively little has been publicly disclosed about Mackenzie’s personal interests or schooling.

Katie has occasionally discussed the experience of raising young children while managing professional commitments, offering followers small glimpses into their family life.

Jackson Grant Miller

Jackson Grant Miller was born in February 2022, becoming the couple’s second child and first son.

His arrival came during a period when Stephen was working outside government following the end of Trump’s first presidential administration.

Jackson is now four years old and has two younger brothers.

Photographs released after Hawthorne’s birth showed the older Miller children participating in family celebrations and welcoming their newest sibling.

Katie has spoken positively about raising multiple young children, describing parenthood as an experience filled with happiness and constant activity.

However, she has avoided publicly sharing extensive information about Jackson’s individual interests or everyday activities.

Hudson Monroe Miller

Hudson Monroe Miller was born in September 2023, making him the couple’s third child and second son.

His arrival expanded the family to five members, including his parents and two older siblings.

Hudson turned three in September 2026 and is now the second-youngest child in the household.

At the time of his birth, Stephen remained involved in conservative political policy and advocacy, while Katie continued developing her career in political communications.

Hudson has appeared in occasional family photographs, but his parents have kept most details about his upbringing private.

When Katie announced their fourth child’s arrival, Hudson appeared alongside Mackenzie and Jackson in pictures celebrating the family’s newest addition.

Hawthorne Hayes Miller

Hawthorne Hayes Miller was born on June 3, 2026, at 9:04 a.m., becoming the youngest member of the Miller family.

Katie officially announced his arrival on June 10 through social media, sharing photographs of the newborn and his older siblings.

In her announcement, she expressed excitement about raising four children aged five and under.

The pictures included Hawthorne resting beside a teddy bear, the older children wearing matching pajamas and a family photograph featuring both parents.

Katie described their home as filled with affection, laughter and happiness following the baby’s arrival.

She also enthusiastically recommended parenthood, calling it a rewarding personal experience.

Hawthorne’s birth received congratulatory messages from friends and public figures, including television personality Emily Compagno and lifestyle entrepreneur Daphne Oz.

Who Is Their Mother, Katie Miller?

Katie Miller is a conservative political communications professional and podcast host who previously served in several prominent government positions.

Born Katie Waldman, she worked as a spokesperson for the Department of Homeland Security and later became press secretary for Vice President Mike Pence during Trump’s first administration.

Katie and Stephen married on February 16, 2020, at the Trump International Hotel in Washington, D.C.

Their relationship developed while both were working in Republican political circles.

After Trump’s return to the White House, Katie briefly worked in the administration before pursuing independent media opportunities, including her podcast.

Her public profile has continued growing alongside her responsibilities as a mother of four.

Family Life and White House Roles

Stephen Miller currently serves as White House deputy chief of staff for policy and homeland security adviser, positions that place him among Trump’s most influential senior aides.

His responsibilities include shaping the administration’s immigration and domestic policy priorities, areas that have attracted significant political debate.

The family’s personal life also briefly entered national headlines following the shooting at the White House Correspondents’ Dinner on April 25, 2026.

Stephen and Katie attended the event while she was approximately eight months pregnant. Gunfire near the ballroom prompted a security response and the evacuation of senior officials.

Video footage showed the couple being protected by security personnel before leaving the venue.

Katie later defended Stephen against criticism of his actions during the evacuation, explaining that security instructions and her limited mobility influenced how they moved.

Several weeks later, the couple welcomed Hawthorne.

Today, Stephen and Katie Miller are raising their four young children while maintaining prominent careers in politics and media. Although their professional activities regularly attract national attention, their children remain a largely private part of their lives.

With Mackenzie, Jackson, Hudson and Hawthorne, the Millers have built a family of six during one of the busiest periods of Stephen’s political career.
