Democratic lawmakers have introduced a joint resolution aimed at ending what they call Trump’s unlawful and unprecedented move to federalize the Metropolitan police department (MPD) in Washington DC.

Representative Jamie Raskin, the ranking member of the House judiciary committee, DC’s non-voting House delegate, Eleanor Holmes Norton, and representative Robert Garcia, ranking member of the House committee on oversight and government reform introduced the resolution on Friday, invoking the District of Columbia Home Rule Act of 1973.

The resolution states that Trump has not demonstrated the existence of any special emergency conditions that would warrant the federalization of the police force. In the Senate, Chris Van Hollen of Maryland will sponsor the resolution.
