Former FBI Director James Comey was interviewed by the U.S. Secret Service on Friday over a social media post that Trump supporters claimed was a veiled threat against the former president.

The post showed the number “8647” spelled out in seashells—interpreted by some as slang for “kill Trump,” the 47th president.

Comey voluntarily met with agents and later took down the post, stating he opposed violence and did not intend any harmful meaning, Reuters has reported.

Homeland Security Secretary Kristi Noem confirmed an ongoing investigation, while Trump accused Comey of intentionally calling for his assassination.
