Prince George’s County Executive Angela Alsobrooks launched her bid Tuesday for the Democratic nomination to replace retiring U.S. Sen. Ben Cardin (D-Md.) in an announcement on Twitter.

In her announcement video, Alsobrooks cited her past accomplishments in reducing crime and strengthening the economy in Prince George’s County. She vowed to continue fighting for her constituents moving forward.

“I am running for Senate to be a voice for families that grew up here and who I have worked for throughout my life,” Alsobrooks said.

Alsobrooks became Prince George’s County’s first female county executive in 2018 after serving as the state’s attorney in the county from 2011 to 2018.

The lifelong Prince Georgian earned convincing electoral victories for county executive in the overwhelmingly Democratic county in 2018 and in her re-election bid in 2022. Alsobrooks won more than 61 percent of votes in 2018 and nearly 91 percent of votes in 2022 in the respective Democratic primaries. She ran unopposed in the general election on both occasions.

Alsobrooks joins an increasingly crowded Democratic field to replace Cardin, which includes Rep. David Trone (D-Md), Montgomery County council member Will Jawando and activist Jerome Segal. Former state Del. Robin Ficker is currently the lone Republican candidate in the race.

If elected, Alsobrooks would be the third-ever Black woman to serve as a U.S. senator and the first to represent Maryland.
