Washington - The leaders of the House and Senate intelligence committees say the terrorism threat against the United States is increasing and Americans aren't as safe as they were a year or two ago.
Senator Dianne Feinstein says there are more terrorist groups than ever, with more sophisticated and hard-to-detect bombs.
The California Democrat says "there is huge malevolence out there".
Republican Mike Rogers says there's enormous pressure on US intelligence services "to get it right, to prevent an attack".
The Michigan Republican says that the job is getting more difficult because al-Qaeda is changing, with more affiliates around the world.
He says those groups once operated independently of but had not joined al-Qaeda.
The lawmakers spoke on CNN's State of the Union in an interview aired on Sunday.
