The Department of Homeland Security said Wednesday that it will add more Transportation Security Administration screeners and more canine teams at airport checkpoints this summer, as part of an effort to help passengers get through those checkpoints more quickly.

“TSA Administrator Admiral Neffenger and I are acutely aware of the significant increase in travelers and longer wait times at airports, and their projected growth over the summer,” Homeland Security Secretary Jeh Johnson said Wednesday. “With this in mind, and given the current threat environment, last month I directed TSA to take a number of steps.”
