Man sent powder letters to politicians in the US with his own name and address on them

A man allegedly sent letters containing a suspicious powder to various recipients, including a U.S. senator, with messages like "HA HA". He claimed he wanted the recipients to take the letters seriously, suggesting the powder resembled anthrax, a dangerous disease. However, he also stated it was a joke. Initial investigations did not confirm the presence of harmful substances. The man was reportedly inspired by similar letters sent to other politicians earlier this month, which were found to be non-threatening. He faces charges for spreading threats and false information and is scheduled to appear in court on Monday.
