Railroads, ports and cargo planes may have been left vulnerable to terrorist attacks while attention was focused on aviation security in the past year, reported the Associated Press. Members of the Senate Committee on Commerce, Science and Transportation said Tuesday they were concerned that Congress had done little to increase security for other kinds of transportation during a hearing to review progress in aviation security, reported the AP. Although the House and Senate passed a bill to make ports less vulnerable to terrorist attack, funding sources for the $1.2 billion cost are still needed. Another bill to increase cargo security has languished, while little has been done to make railroad passengers secure, said the AP. "We can't see this as just an aviation issue," said Transportation Security Administration Chief James Loy during the committee hearing.
