Twitter Cuts Off US Intelligence Agencies from Twitter Firehose?

Has Twitter cut off US intelligence agencies’ access to its firehose? “Twitter said it has a long-standing policy barring third parties, including Dataminr, from selling its data to a government agency for surveillance purposes. The company wouldn’t comment on how Dataminr—a close business partner—was able to provide its service to the government for two years, or why that arrangement came to an end.”
