(CNN)White supremacist extremists will remain the deadliest domestic terror threat to the United States, according to the Department of Homeland Security's first annual homeland threat assessment, which details a range of threats from election interference to unprecedented storms.

Am I reading this correctly? Is this the Department of Homeland Security's first ever annual homeland threat assessment? The department created to assess homeland threats finally after 18 years produced it's first annual threat assessment? What have they been doing since 2002?
