Some people bought and sold a lot of oil just before the US president said something important about Iran. The price of oil went down very fast after his message. The people who made these trades made a lot of money.

Some people think these traders knew about the president’s message before he told everyone. They think this is not normal. Some people want to know if this is fair or not.

The government says it does not allow people to use secret information to make money. Some people want an investigation to find out what happened. The price of oil went up again after Iran said there were no talks.
