Homeland Security Secretary Michael Chertoff says security is being increased at U.S. airports and transit systems as the Fourth of July holiday approaches, including more air marshals on overseas flights.
In the wake of three attempted terror plots in Britain, Chertoff says there's concern about possible copycat plots in the US.
"Well, let me remind everybody, of course, that the threat level for aviation has been at orange since last August, when we had the foiled bombing plot involving airlines from the U.K. to the United States. But we do not have any specific credible evidence that there's an attack focused on the United States at this point. What we have done is we've taken pre-existing plans for heightened airport security and we've put those into effect. And that's why people should expect to see some visible signs of increased security at airports all across the country," said Chertoff.
Chertoff also notes that the same security operations will be place at various rail and other mass transit locations as we head into the holiday.
