New Measures for Rerouting Flights and Passengers from China

The Department of Homeland Security (DHS) announced over the weekend that to combat the spread of the Coronavirus, all flights departing after 5 pm EST on February 2, 2020 from China, and all passengers traveling from China will be routed through one of 11 U.S. airports where they will be required to make first entry and be screened:

  • John F. Kennedy International Airport (JFK), New York
  • Chicago O’Hare International Airport (ORD), Illinois
  • San Francisco International Airport (SFO), California
  • Seattle-Tacoma International Airport (SEA), Washington
  • Daniel K. Inouye International Airport (HNL), Hawaii
  • Los Angeles International Airport, (LAX), California
  • Hartsfield-Jackson Atlanta International Airport (ATL), Georgia
  • Washington-Dulles International Airport (IAD), Virginia
  • Newark Liberty International Airport (EWR), New Jersey
  • Dallas/Fort Worth International Airport (DFW), Texas
  • Detroit Metropolitan Airport (DTW), Michigan

Note that per DHS notice, the authorization for rerouting to EWR, DFW, and DTW begins February 3, 2020. 

Travelers will pay no additional costs for any rerouting. Notably, flight crew, and flights carrying cargo-only are excluded from these new measures.

Screening, Quarantine Requirements Imposed; Foreign Nationals Who Visited China Will Be Denied Entry

These 11 airports will implement the administration’s recently announced Coronavirus screening and quarantine protocol, under which:

  • U.S. citizens who have been in Hubei province within 14 days of their return will be subject to up to 14 days of mandatory quarantine.
  • U.S. citizens who have been in other areas of mainland China within 14 days of their return will undergo proactive entry health screening and up to 14 days of self-quarantine with health monitoring.
  • Foreign nationals (other than immediate family of U.S. citizens, permanent residents, and flight crew) who have traveled in China within 14 days of their arrival will generally be denied entry into the U.S.

These restrictions will have immediate and wide- ranging impacts for businesses operating internationally, particularly those that rely on U.S. citizens and foreign nationals to travel to and from China and the United States. Given the fast-changing nature of this outbreak, multinational companies should continue to seek guidance from counsel to assist their employees, contractors, suppliers, and business visitors as they adjust their international business needs in accordance with applicable laws and regulations.

A Sign of What’s to Come? Court Dismisses FCA Retaliation Complaint Based on Alleged Discriminatory Use of Federal Funding

On November 7, 2025, in Thornton v. National Academy of Sciences, No. 25-cv-2155, 2025 WL 3123732 (D.D.C. Nov. 7, 2025), the District Court for the District of Columbia dismissed a False Claims Act (FCA) retaliation complaint on the basis that the plaintiff’s allegations that he was fired after blowing the whistle on purported illegally discriminatory use of federal funding was not sufficient to support his FCA claim. This case appears to be one of the first filed, and subsequently dismissed, following Deputy Attorney General Todd Blanche’s announcement of the creation of the Civil Rights Fraud Initiative on May 19, 2025, which “strongly encourages” private individuals to file lawsuits under the FCA relating to purportedly discriminatory and illegal use of federal funding for diversity, equity, and inclusion (DEI) initiatives in violation of Executive Order 14173, Ending Illegal Discrimination and Restoring Merit-Based Opportunity (Jan. 21, 2025). In this case, the court dismissed the FCA retaliation claim and rejected the argument that an organization could violate the FCA merely by “engaging in discriminatory conduct while conducting a federally funded study.” The analysis in Thornton could be a sign of how forthcoming arguments of retaliation based on reporting allegedly fraudulent DEI activity will be analyzed in the future....
