Story summary

Matthew Unglesbee, a 37-year-old man from Quincy, Illinois, was arrested and charged with sending letters containing white granular substances to four Democratic members of Congress. The letters were addressed to Rep. Mike Quigley, Rep. Brad Schneider, Rep. Jan Schakowsky, and Sen. Tammy Duckworth in Chicago. Unglesbee allegedly wrote his own return address on the envelopes, leading authorities to apprehend him after the FBI received a tip from someone who overheard him discussing the letters at a restaurant.

According to a criminal complaint unsealed on October 27, 2026, preliminary tests by the FBI revealed that the white substance was salt. Unglesbee told investigators he mailed the letters as a joke because he knew it could cause concern due to the resemblance of salt to more dangerous substances like anthrax.

The letters contained notes reading "HA HA" and "Hah enjoy the gift," and prompted hazardous materials (hazmat) teams to respond to two of the offices. Unglesbee faces charges of mailing threatening communications and perpetrating a hoax, reflecting the serious security concerns these incidents raised in Congress and among law enforcement officials.
