The U.S. Federal Aviation Administration lifted a nationwide halt on domestic flight takeoffs within hours after imposing it over a communications outage, CNN reported. The action led to thousands of delays and cancellations at major airports. An airline source said the cause was a network router problem that spread nationwide. Cirium estimated about 1.5 million passengers were stranded. Homeland Security Secretary Markwayne Mullin said it was not tied to a threat or a Microsoft outage, and investigators said it did not appear to be a cyberattack.

U.S. President Donald Trump did not use the terms “cryptocurrency” or “digital assets” at a White House cybercrime roundtable focused on large-scale online fraud and the government’s response. He instead referred to fraud-linked assets as “cybercurrency,” while other participants also avoided the industry’s common terms. The meeting drew renewed attention to conflict-of-interest controversy surrounding crypto businesses involving Trump and his family, and to continued enforcement actions tied to foreign-linked fraud and money laundering.
