The Maryland Attorney General's Office is working hard to protect Maryland residents from the harmful actions of the Trump administration. Among other actions, Maryland – as lead plaintiff – is spearheading a coalition of 20 attorneys general in challenging unlawful mass layoffs of thousands of federal probationary employees, terminations that are draining state resources and threatening our economy. Maryland has also joined other multistate lawsuits to challenge the administration's harmful policies, including the dismantling of the Department of Education, freezes on essential federal funds and cuts to medical research, the unlawful acts of Elon Musk's so-called Department of Government Efficiency (DOGE), and President Trump's attempt to overturn the Fourteenth Amendment and end birthright citizenship.
If the Trump administration continues to take actions that hurt our State and its residents, our Office will stand up for Marylanders and challenge those actions in court.
