AZUZ: Investigators are trying to figure out what led to an accident yesterday that involved a large garbage truck and train carrying dozens of members of the U.S. Congress.

Almost 100 Republicans, including senators, representatives and House Speaker Paul Ryan were headed to a retreat in West Virginia when the train they were traveling on collided with the tractor trailer. The driver of the truck was killed. Six other people, including two Amtrak crew members were hospitalized.

Except for some minor injuries, all the members of Congress were reportedly OK. Several of them thanked the first responders and asked people to pray for the victims of the accident and their families. And because some of the lawmakers are doctors or have medical training, they were able to help those who were hurt.

U.S. President Donald Trump said the Republican lawmakers conference would go on as planned.

The director of the CDC, the U.S. Centers for Disease Control, resigned from her job on Wednesday. Dr. Brenda Fitzgerald, an obstetrician/gynecologist from Georgia, had served as head of the CDC since she was appointed last July. But about a month after that, she reportedly bought stock in a number of companies that included Japan Tobacco, one of the largest tobacco businesses in the world. That's according to a report that came out earlier this week from "Politico", a political news organization.

Tobacco smoking is the leading caused of preventable death in the U.S. And Dr. Fitzgerald has spoken out against it and offered the government's help in getting people to quit. So, critics say her stockholding in a tobacco company was a conflict of interest.

A spokesman for the U.S. Department of Health and Human Services, which oversees the CDC, says the stock purchase wasn't made directly by Dr. Fitzgerald, that her financial account manager did it. And another former director of the CDC says he believes that Fitzgerald didn't know that her financial manager had made the investment in Japan Tobacco, and that when she found out, she said to sell the stock.

Another doctor has been brought in to head up the CDC until Fitzgerald's replacement is named.
