A note containing white powder and "hateful language" sent to the South Side office of U.S. Rep. Bobby Rush Thursday prompted a HazMat response.
Firefighters responded shortly before noon to the Democratic congressman's, at 700 E. 79th Street, after the powder was found in a letter, fire department spokeswoman Eve Rodriguez said.
The powder was determined to be a harmless household product, Fire Media Affairs Director Larry Langford said.
"There is absolutely, positively no threat at all," Langford said, though adding the letter included "hateful language."
A couple of employees in the office opened the letter and alerted authorities. No one was injured, according to Langford.
