The Department of Homeland Security is ramping up airport security following the suspected bombing of a Russian plane over Egypt. The new security focuses on certain overseas airports.

As Egyptian authorities investigate whether an airport insider may have planted a bomb on the doomed airliner, U.S. lawmakers and aviation officials are raising questions about security at American airports. They say dozens of current airport employees are being screened for possible ties to or sympathies with extremist groups.

According to news reports, surveillance video at the Sharm el-Sheikh airport is being scrutinized for someone with access to the plane on the airport ramp. While no official determination has been made, U.S. and U.K. officials have said they believe it’s likely a bomb brought down the flight last Saturday, killing more than 200 people.

With the recent congressional reports and hearing on airline security due to an undercover operation revealing that the TSA failed 95% of the time when detecting fake explosives, new action is being called into place.

“It’s no secret that people interested in harming America are coming up with creative ways to circumvent the existing security measures,” House Committee on Government Oversight and Reform Chairman Rep. Jason Chaffetz, R-Utah, said at the hearing.

In airports both here and abroad extra attention will be paid to bags, including extra scrutiny of the list of passenger names to make sure they match the name on all the checked baggage.

Security will focus on airport workers who are poorly paid and could be susceptible to terrorists bribes.
