Chicago, IL, October 16, 2026 —
Four Democratic members of the U.S. House representing the Chicago area, along with offices of the Illinois State Board of Elections and the Cook County Treasurer, received suspicious letters, according to the information provided. The letters were found not to contain harmful substances. Law enforcement investigations, including an FBI investigation, remain ongoing.
The incidents are part of a broader pattern of threatening mail sent to election offices and members of Congress nationwide in the lead-up to Election Day. The available information does not specify when the letters were received or identify the representatives involved. It also does not describe the letters or explain how they were determined not to contain harmful substances.
No further details were provided about the investigations, including which agencies are handling particular cases, whether the incidents are being treated as connected, or whether anyone has been identified as responsible. The information also does not describe any public safety measures taken at the affected offices.
The reported incidents involve both elected officials and offices connected to election administration and county government. The broader nationwide pattern provides context for the Chicago-area reports, but the available details do not establish whether the local letters were linked to other mailings. Investigations are continuing, and no outcome beyond the finding that the letters did not contain harmful substances was provided.
