Alston was a member of the House of Delegates from 2011 to 2013 and served on the Judiciary committee. She was a member of the
Prince George's County Delegation, the Women's Caucus, and the
Legislative Black Caucus of Maryland. She won election to the seat and was sworn in on January 11, 2023, and has since served in the Health and Government Operations Committee. In 2024, Alston applied to run as a delegate to the
Democratic National Convention pledged to
Joe Biden, but was denied by the
Maryland Democratic Party.
Marriage equality During the 2011 legislative session, Alston was a co-sponsor of "Religious Freedom and Civil Marriage Protection Act". A similar bill was filed in the Maryland Senate (SB 116 -
Civil Marriage Protection Act) and was assigned to the House Judiciary Committee, the committee on which Alston served. During the committee voting session on SB 116, Alston revoked her co-sponsorship and instead offered an amendment to change the bill from
same-sex marriage to
civil unions. The amendment failed, and Alston then voted against the bill. Despite Alston's vote, SB 116 was approved by the committee 12-10 and was forwarded to the full House of Delegates for final approval, but the bill was eventually sent back to committee, effectively terminating the bill for the session. Alston voted against the Civil Marriage Protection Act in committee when it was re-introduced in the 2012 legislative session, but voted for the bill after it was amended to block the bill from going into effect if efforts to bring it to a referendum were being litigated. ==Criminal charges==
