In the USA, people vote soon. These are mid-term votes. People have big worry now. Unknown persons send strange letters. The letters go to offices of politicians. Election offices get mail too.
The letters have white powder in them. This happens in Louisiana and Oklahoma. People must leave the rooms. The police check the letters. One letter in Ohio is safe early. No person has hurt so far.
The FBI police search for the persons. The exact powder is still unclear. In the past, such letters exist before. Back then, some letters have a bad drug. The police warn all workers in the offices.
