Who is Ed Martin and what concerns does his appointment as U.S. Attorney for Washington, D.C. raise?

Ed Martin, nicknamed 'The Eagle,' is a controversial figure appointed as U.S. Attorney for Washington, D.C. He's known as a 'stop the steal' advocate, election denier, and defender of January 6th defendants. Martin is viewed as a particularly ardent MAGA loyalist who was put in place shortly after Trump's inauguration and expedited the dropping of Capitol riot cases. His appointment has raised significant concerns among longtime, tenured members of the Washington, D.C. prosecutor's office. Having someone with Martin's political background in charge of prosecutions in the nation's capital is seen as problematic for career federal prosecutors who prioritize the impartial administration of justice.
