The House Oversight and Government Reform Committee voted on Monday night to block the District of Columbia’s assisted dying law from going into effect Saturday. The Committee voted 22-14 to advance H.J. Resolution 27, which would overturn Washington, D.C.’s, Death with Dignity Act. It was one of only a handful of times in the four-decade history of D.C. home rule that members of Congress have tried to use their constitutional power to overturn a city law. Despite the committee vote, it is not clear whether Congress will be able to overturn the D.C. law. Both the full House and Senate would have to vote to block it by Friday, when a 30-day window for congressional review expires, according to D.C. officials.
