Dunn joined the
United States Capitol Police in 2008. From 2009 to 2023, he worked as a first responder providing security around the exterior of the
United States Capitol and as a member of the Capitol Police Crisis Negotiation Team. He was commissioned as an officer as a
private first class in 2011,[6] and was named a
field training officer in 2017.[9] In November 2021, Dunn ran against Gus Papathanasiou in an election to chair the U.S. Capitol Police Labor Committee.[10][11] Papathanasiou defeated Dunn in a secret ballot.[12]
Dunn, D.C. Metropolitan Police Officer
Michael Fanone, and Gladys Sicknick, the mother of
Brian Sicknick, advocated for the creation of a
January 6 commission, to investigate the attack in a method similar to the
9/11 Commission in meetings with
U.S. Senators of the
Republican Party.[17] He was in attendance when the U.S. House approved the formation of the
United States House Select Committee on the January 6 Attack.[18] He testified to the committee alongside Fanone, Capitol Police
Sergeant Aquilino Gonell, and D.C. Metropolitan Police Officer Daniel Hodges in its preliminary hearing on July 27, 2021. In his testimony, Dunn said that rioters had used racial slurs against him during the attack[19][20] and that he has attended psychotherapy and engaged in peer support to help him process the trauma he experienced.[21] The four officers were given a front-row seat to all of the committee's public hearings in 2022.[22] Dunn has stated his belief that
Donald Trump should be arrested for his conduct preceding the riot.[23]
Dunn testified in the 2022 trial of the Oath Keepers for seditious conspiracy for their actions relating to the Capitol attack. Though they claimed that they were trying to assist the officers during the attack, Dunn refuted their claims.[14] The trial resulted in the convictions of Meggs and
Stewart Rhodes.[24]
Dunn wrote a memoir, titled Standing My Ground, which was published on October 24, 2023, by
Hachette Books.[3][25] He resigned from the Capitol Police on December 17, 2023.[26]
In October 2023, after U.S. Representative
John Sarbanes announced that he would not run for re-election in 2024, Dunn expressed interest in a potential run for his seat in
Maryland's 3rd congressional district.[27] He officially entered the race on January 5, 2024, running in a crowded Democratic primary field that includes five state legislators—
Mark S. Chang,
Sarah Elfreth,
Terri Hill,
Clarence Lam, and
Mike Rogers.[28] If elected, Dunn would have been the second Capitol Police officer elected to Congress after
Harry Reid's initial election to
Nevada's 1st congressional district in
1982.[29][30] As a result of his strong fundraising ability and online presence,[31] Dunn was seen as a frontrunner in the race alongside Elfreth and Lam.[32][33] As of April 2024, Dunn led his opponents in fundraising with $4.5 million in contributions.[34]
During the Democratic primary, Dunn campaigned on a platform involving democracy-related issues, abortion, infrastructure, health care laws, and gun reform.[35][36] He received endorsements from various Democratic celebrities, including U.S. representatives
Nancy Pelosi,
Jim Clyburn,
Adam Schiff, and
Jasmine Crockett,[37][38][39] but none from elected officials within the district.[34] Dunn pledged not to accept campaign contributions from corporate
political action committees (PACs) and criticized
AIPAC for getting involved in the primary by running ads for Elfreth.[40] He also expressed support for Israel and its right to defend itself amid the
Israel–Hamas war, opposing conditioning U.S. aid to Israel. Dunn also voiced support for a bill to provide $74 billion in funding to Ukraine and Israel and humanitarian aid to the
Gaza Strip.[41][42] Dunn supported an amendment introduced by U.S. senator
Chris Van Hollen that would condition U.S. foreign aid on a country's compliance with international law,[43] but later reiterated that he would only support requiring countries to comply with existing conditions as opposed to establishing new conditions.[44]
Dunn was defeated in the Democratic primary election by state senator
Sarah Elfreth on May 14, 2024, placing second with 25.0 percent of the vote.[45] He conceded defeat that night and endorsed Elfreth in the general election.[46] Following his defeat, Dunn started his own political action committee, Democracy Defenders PAC, to support candidates running against pro-Trump Republicans.[47] He also campaigned for President Biden's
2024 reelection campaign in
swing states alongside fellow former U.S. Capitol Police officers who were present at the U.S. Capitol during the January 6 Capitol attack.[48]
Personal life
Dunn married Danyel Moncree on June 11, 2009,[49] but are now divorced.[50] They have a daughter.[51] Dunn currently lives in
Montgomery County, Maryland, and pledged to move to somewhere within Maryland's 3rd congressional district if elected to Congress.[28]
In November 2011, Montgomery County police officers were called to Dunn's home to respond to a violent domestic assault involving Dunn and his then-wife stemming from an argument about his 16-year-old stepson not doing the dishes. According to the internal memo obtained by Punchbowl News, Dunn's wife allegedly waved a kitchen knife in Dunn's direction, prompting him to retrieve his service weapon and rifle, which were stored in a department-issued lockbox with a broken locking mechanism, a violation of U.S. Capitol Police policy that led to a four-day suspension without pay. When police arrived at the scene, both Dunn and his wife had minor scratches on their arms and neither were willing to press charges over the incident. In a statement to Punchbowl, Dunn and his wife acknowledged the argument and memo, but denied having been physically violent to each other.[52]
Honors
Along with other officers who protected the Capitol during the attack, Dunn was awarded the
Congressional Gold Medal on December 6, 2022.[53]
