Appeals court blocks construction of White House ballroom

(WASHINGTON) — A federal appeals court issued a ruling Friday blocking the construction of President Donald Trump’s $400 million White House ballroom, concluding that congressional approval is needed for the project. 

Judges Patricia Millett and Bradley Garcia rebuked President Trump for making the unprecedented changes to the historic structure without consulting Congress.

“Each President is a temporary tenant, not the owner, of the White House and its Executive Residence. The President has no — and claims no — constitutionally assigned authority over that property,” they wrote. 

They concluded that the National Trust for Historic Preservation, which sued to block the construction, demonstrated that only Congress has the authority to approve the changes, and that it never delegated that authority to Trump. 

“Whether or not a massive ballroom should be constructed is for Congress to decide and is not a matter for Executive self-help,” they wrote. 

“This holding has nothing at all to do with whether the proposed ballroom is desirable, or not, as a matter of policy. This ruling does not even necessarily mean that the Defendants may not ultimately construct the ballroom. What it does mean is that the Defendants may not do so during the district court’s expeditious litigation without securing Congress’s authorization, as the Constitution and laws require,” they said. 

Trump, in a social media post, said he would immediately appeal the ruling to the Supreme Court.

Judge Neomi Rao dissented from the majority, concluding that the National Trust for Historic Preservation does not have the jurisdiction to bring the lawsuit. She also argued that it is “likely within the President’s authority to make improvements to the Executive Residence” and that the Trump administration would be harmed by the blocking construction. 

“The district court elevated the aesthetic displeasure of a single passerby over the government’s security interests in the ballroom and the security risks of leaving an open construction site at the President’s home and office,” she wrote. 

“In deciding the ballroom construction “has to stop!” the district court transgressed the equitable authority of the federal courts. The preliminary injunction is a clear abuse of discretion and must be vacated,” Judge Neomi Rao wrote.

The ruling does not take effect for two weeks, allowing time for the Trump administration time to appeal.

The White House announced the construction of the 90,000-square foot ballroom last July, and demolition began suddenly on the East Wing in late October when workers were spotted tearing down that wing of the White House.

While the appeals court acknowledged the national security concerns associated with the East Wing renovations, the majority said that those concerns are not an “automatic get-out-of-law-free card” to violate the law. 

“Congress has not given the Park Service authority, specifically and expressly, or otherwise, to raze protected historic sites in the name of presidential functions or national security,” wrote Judges Patricia Millett and Bradley Garcia. 

The majority added that national security concerns are exactly the reason why Congress should be involved in the project. 

“It is Congress’s job to ensure that any major construction and security projects at the White House will protect the safety of all Presidents, present and future, while preserving the historical and architectural significance of that unique location. Congress cannot perform its constitutional function when the Executive chooses to proceed wholly unilaterally,” they wrote. 

Judge Neomi Rao disagreed with her colleagues, saying that halting the construction “inevitably extends the time during which the President’s residence remains less secure.”  

“The security risks presented by large offsite events involving the President were unfortunately confirmed by the assassination attempt against President Trump at the Washington Hilton during the White House Correspondents’ Dinner,” she added in a footnote. 

Judge Rao criticized the analysis reached by her colleagues, arguing that the harms suffered by the Trump administration from a delay would outweigh the “aesthetic harm” cited by the National Trust for Historic Preservation. 

“The government should not be forced to rely on the district court’s architectural approval to secure the President’s home and office,” she wrote. 

The district court judge who originally blocked the construction of the ballroom modified his injunction in April to allow work related to security to proceed, while the ballroom-related construction was halted.

Even if the Supreme Court does not side in Trump’s favor, the current legal posture would allow “below-ground construction of national security facilities, work necessary to provide for presidential security, and construction necessary to protect and secure the White House and the construction site itself,” the judge wrote.

How one Davis lab is trying to stop California’s golden mussel invasion

Click here for updates on this story    DAVIS, California (KOVR) -- The first known detection of the invasive golden mussel in all of North America happened in California.This invasive species has prompted states of emergency, both in San Joaquin County, where they were found at the Port of Stockton, and in Yolo County, where they were found to have spread to the Port of West Sacramento. It's posing a huge threat to Sacramento-San Joaquin Delta waterways.It's threatening billions of dollars in losses for farmers and could choke California's water supply. Working to help stop it is the Davis-based Invasive Species Corporation, which is stepping up with a possible solution. Research scientist Brady Hirschfeld studies how to stop the rapid golden mussel invasion."It's really rewarding to be on this side of things," Hirschfeld said. "I'm really proud to be part of the solution to kill golden mussels."The patent-protected product being tested is zequanox, created first to kill other invasive zebra and quagga mussels. Now, it's being redeveloped and retested to root out the goldens, which are notoriously resilient and hard to kill.Also trying to slow down the spread is Pam Marrone."These mussels are ranked the top five worst invasive species on the planet, causing many billions of dollars of damage," Marrone said. "So we're really tackling a big problem. We're excited we can do that."She is working to get zequanox approved for full use in golden mussels."We're alone. In fact, we're the only company, I think, in the world that's actually tackling invasive species in water," Marrone said.How it works In the lab, the mussels are exposed to zequanox, where Marrone says, "they'll eat it, it'll slowly take effect and they'll die."Marrone noted that zequanox is biodegradable, with no impact on surrounding creatures and habitat."It doesn't harm fish or the native mollusks or anything, anything else," he said.The test subjects were collected in Stockton, and a local marina there will be the first site to test zequanox on golden mussels in the wild this fall.The city's port is ground zero for the delta invasion."Eradication is, in my opinion, unthinkable. They're here to stay," said San Joaquin County Supervisor Mario Gardea. "It's about mitigation."Gardea sits on a board committee to tackle golden mussels and said the response requires local, state and federal action."Anything that touches our delta, anything that has to do with water is going to be affected," he said.Golden mussels can eradicate fish populations and erode delta habitats, and California farmers could lose their water.Marrone said the impact on community members could mean water flows being stopped due to infestations.Next steps involve getting zequanox approved for use in golden mussels through the California Environmental Protection Agency and hoping to get this rolled out in local waterways next year, possibly sooner, if California approves an emergency use.Please note: This story was provided to CNN Wire by an affiliate and does not contain original CNN reporting.
