Washington, D.C., Mayor Muriel Bowser scheduled a news conference on Wednesday afternoon to address the Trump administration’s decision to assume control of local law-enforcement operations in the nation’s capital. Federal authorities began overseeing policing in the District after a White House directive issued earlier this week, superseding the Metropolitan Police Department in key public-safety functions. The mayor’s briefing comes one day after President Donald Trump publicly suggested imposing the death penalty on anyone convicted of murder in the District, a proposal that would overturn the city’s long-standing ban on capital punishment. Bowser is expected to outline how city agencies will coordinate with federal forces and to detail the implications of the president’s remarks for District governance and criminal-justice policy.
