WASHINGTON — Denver Mayor Mike Johnston regularly games out responses to threats like destructive tornadoes or hazardous waste leaks. He's added a new potential menace: the federal government.
When President Donald Trump deployed National Guard troops to some U.S. cities last year over the objection of local leaders, Johnston said his tabletop exercises expanded to consider what might happen if federal officials took aim at Denver, which the Trump administration has sued for limiting cooperation on deportations. The city now prepares for the impact of federal activity on everything from access to schools and hospitals to interference with elections.
''We used to prepare for natural disasters,'' Johnston, a Democrat, said in an interview. ''Now we prepare for our own federal government.''
A half-dozen state and local officials from both major political parties over the past week described an increasingly hostile relationship with Washington. While there's inherent tension between city, state and federal governments over power, politics and money, the current dynamic is unlike anything they've experienced, particularly after federal agents killed two U.S. citizens in Minneapolis last month.
While partnerships are still in place, the officials said the Minneapolis killings have hardened opposition to excessive federal power.
''This is unprecedented,'' said Jerry Dyer, the Republican mayor of Fresno, California, and a former police chief. ''I've never seen federal law enforcement come to the cities, whether it's National Guard or ICE, and police cities without a level of cooperation from local police.''
GOP long sought to empower local governments
The tensions have upended longtime Republican arguments that the federal government should leave local governance to the states under the 10th Amendment to the U.S. Constitution. Now a Republican president is articulating a muscular federal approach over the protest of Democrats.
