Education In September 2019, Lopez joined Maryland Attorney General
Brian Frosh and 43 other members of the Maryland General Assembly in co-signing a letter to U.S. Education Secretary
Betsy DeVos asking for information about her implementation of the federal
Public Service Loan Forgiveness program. During the 2021 legislative session, Lopez endorsed a bill to expand
collective bargaining rights to employees at
Maryland's 16 community colleges. In April 2024, Lopez expressed concerns with efforts to
ban books in public schools and libraries and called for federal protections against book bans. She also supported increasing funding for local school districts and teachers, and hiring more support personnel in schools.
Gun policy In August 2019, Lopez said she opposed the
Maryland State Police's decision to repeal limits for
concealed carry permits for business owners, pointing out that the decision followed mass shootings in
El Paso, Texas, and
Dayton, Ohio. In 2020, Lopez introduced a bill requiring firearms to be stored in an area where a minor could not gain access to it. During the 2021 legislative session, Lopez introduced legislation to ban
privately made firearms. The bill failed to pass out of committee. She reintroduced the bill in 2022, during which it passed and became law without Governor Hogan's signature. Following the bill's passage, Lopez was invited to the
White House by President
Joe Biden, where he announced a new
United States Department of Justice rule regulating privately made firearms.
Health care During the 2026 legislative session, Lopez introduced a bill that would require Medicaid and other state programs to cover the cost of monitoring devices for individuals with a higher chance of
elopement.
Immigration During the 2026 legislative session, Lopez introduced a bill that would prohibit state employees from knowingly aiding
U.S. Immigration and Customs Enforcement unless presented with an official judicial warrant.
Israel Lopez supports a
two-state solution to the
Israeli–Palestinian conflict. In October 2023, amid the
Gaza war, Lopez said she supported Israel's right to defend itself and called for humanitarian aid to Palestine.
Policing reform In June 2020, Lopez pledged to stop taking campaign contributions from the
Fraternal Order of Police. During the 2023 legislative session, Lopez introduced a bill to allow municipalities to establish police accountability boards.
Social issues In 2019, Lopez introduced a bill to expand the state's child pornography laws to include
lascivious behavior and
computer-generated images. The bill unanimously passed the Maryland General Assembly. In May 2022, following the leak of a draft majority opinion for the
U.S. Supreme Court case ''
Dobbs v. Jackson Women's Health Organization'', Lopez sent a letter on the behalf of the Women's Legislative Caucus of Maryland to Governor
Larry Hogan, asking that he release the $3.5 million in funds to train abortion care providers as part of the Abortion Care Access Act. Hogan denied her request, effectively delaying the law's implementation until July 2023. During her 2024 congressional campaign, Lopez said that she would support codifying the
Roe v. Wade decision on the federal level. The bill passed and was signed into law by Governor
Wes Moore, but was blocked from going into effect by federal health officials, who said the program "exceeds permissible use" of the fees collected by the
Affordable Care Act. During the 2023 legislative session, Lopez introduced a bill prohibiting the
Maryland Department of Public Safety and Correctional Services correctional staff from discriminating against
gender nonconforming individuals and would allow these individuals to be housed in a facility that aligns with their
gender identity. During the 2026 legislative session, Lopez introduced a bill that would expand the state's
311 system statewide through the use of
AI chatbots and voicebots. ==Personal life==
