In an interview with CNN's "State of the Union," Homan told host Dana Bash that he is devising a plan with Tedd Lyons, acting director of Immigration and Customs Enforcement, and Ha Nguyen McNeill, acting administrator for TSA, to determine where agents would best fit at airports across the nation. That plan, Homan said, will be finalized Sunday and go into effect Monday.

"We'll have a plan by the end of today," Homan said, including "what airports we're starting with."
