Her Family Connection to Martha MacCallum
Elizabeth is the eldest of Martha MacCallum and Dan Gregory’s three children. Her younger brothers are Reed and Harry Gregory. Family and congressional records identify her complete name as Elizabeth Bowes Gregory, while professional records and news coverage generally use Elizabeth Gregory.
A St. Lawrence University profile of MacCallum described Elizabeth as 21 and named her brothers as Reed and Harry. The profile appears to reflect the family’s circumstances around 2017, so the age listed there should not be treated as her current age or as confirmation of a precise birth date.
MacCallum also discussed spending part of the COVID-19 pandemic in New Jersey with her husband and their three children during a 2020 interview. However, Elizabeth has not built her public identity through interviews about her family or private life. Most reliable information about her concerns her professional work in Republican political communications.
Press Work for Marsha Blackburn
Gregory’s documented political career includes work on Marsha Blackburn’s 2018 U.S. Senate campaign in Tennessee. Campaign-employment records list her as a press secretary from July through December 2018.
Following Blackburn’s election, Gregory moved into her official Senate office. Congressional expenditure records identify her as a press secretary beginning in January 2019 and continuing through later reporting periods that extend into January 2021.
The two positions represented different sides of political communications. Her campaign role involved speaking for a candidate seeking office, while her subsequent congressional position supported the communications operation of an elected senator.
Payment figures recorded in congressional expenditure reports apply to individual reporting periods. They should not be interpreted as Gregory’s annual salary, total income, or net worth.
Campaign Roles With David Perdue and Marco Rubio
Gregory later worked as a press secretary for David Perdue’s Senate campaign in Georgia. Employment records place her in that position from November 2020 through January 2021.
Those dates overlap with the closing period reported for her work in Blackburn’s Senate office. The available records establish the dates attached to both positions but do not explain whether the overlap resulted from reporting schedules, a rapid transition, or work performed for both organizations.
Her next documented position was with Marco Rubio’s Senate campaign in Florida. Gregory served as communications director from June 2021 through December 2022.
That appointment marked a progression from her earlier press-secretary roles. As communications director, she held a broader campaign title, although publicly accessible records do not provide a detailed account of her internal responsibilities or the staff she managed.
Senior Role in Dave McCormick’s Senate Campaign
Gregory joined Dave McCormick’s Pennsylvania Senate campaign in February 2023. Her recorded position combined the titles of deputy campaign manager and communications director, placing her within the campaign’s senior operation.
Her role became particularly visible during the closely contested 2024 Pennsylvania Senate election. News organizations identified Gregory as McCormick’s communications director and published statements she issued during disputes over mail ballots, provisional ballots, and the vote-counting process.
After the Associated Press called the race for McCormick on November 7, Gregory said he was honored to have received support from voters across Pennsylvania and looked forward to serving them in the Senate. The projection came before the state completed its official certification process.
She spoke for the campaign again following a November 18 Pennsylvania Supreme Court ruling concerning mail ballots with missing or incorrect dates. Her response presented McCormick’s position on the decision and referred to his expected Senate oath.
These statements show that Gregory acted as a public spokesperson during one of the campaign’s most consequential periods. Because she delivered them on McCormick’s behalf, they document her professional responsibilities rather than her independent personal views.
McCormick ultimately won the election, and Gregory’s recorded campaign employment continued through April 2025. Available official information does not establish that she subsequently joined his Senate staff.
Her Advisory Work With ColdSpark
Gregory’s professional record also identifies her as a senior adviser at ColdSpark from January through April 2025. ColdSpark is a political consulting and public affairs firm, making the position consistent with her campaign communications experience.
The dates overlap with the final months of her recorded McCormick campaign role. Public employment summaries do not explain whether the ColdSpark position was connected to her campaign responsibilities or represented a separate arrangement.
April 2025 is the end of the clearly documented employment timeline available for Gregory. Later descriptions have connected her with McCormick in an advisory capacity, but no official announcement has established her precise position after that date.
Elizabeth Bowes Gregory’s Documented Career
Although Elizabeth Bowes Gregory is widely recognized as Martha MacCallum’s daughter, her professional history extends beyond that family connection. She has worked in campaign and congressional communications across several election cycles, beginning with press roles and later advancing to communications director and deputy campaign manager.
Her most publicly visible work came during Dave McCormick’s 2024 Pennsylvania Senate campaign, when she represented the campaign during post-election legal and vote-counting disputes. Together with her earlier roles for Blackburn, Perdue, and Rubio, that work establishes a sustained career in Republican campaign messaging, media relations, and political communications.
