Brian M. Crosby

During the 2022 legislative session, Crosby voted for a bill that would prevent school boards from discriminating against people on the basis of race, ethnicity, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, or disability; the bill passed the House of Delegates by a vote of 94-36 and the Senate by a 34-13 vote, and became law without the governor's signature. During a debate on the bill, Crosby voted against an amendment that would have blocked public schools from discussing gender and sexuality in the classroom. The amendment failed by a 37-95 vote. He also voted against an amendment that would prohibit transgender students from competing on girls' sports team in schools, which was defeated in a 42-91 vote.

Crosby supports the Blueprint for Maryland's Future, a sweeping education reform bill passed by the legislature during the 2020 legislative session that would provide schools with $3.8 billion a year for 10 years. He criticized a bill introduced that year that would allow teachers to carry guns in schools, later calling it the "dumbest policy in American history. Teachers sign up to teach. They don't sign up to go through combat trauma."

In September 2020, Crosby criticized the Maryland State Board of Elections for only having one early voting center in his county for the 2020 United States presidential election.
