The problem of foreign fighters taking up arms alongside the ISIS terror army is growing, according to a senior member of Congress, and more than 150 Americans are now among them.
ISIS operates a 'virtual caliphate' online, California Republican Rep. Ed Royce said Thursday, recruiting foreigners at an 'unprecedented rate.'
'Some 20,000 foreign fighters from more than 90 countries now make up its ranks' including at least 3,400 from the West and more than 150 Americans,' Royce said during a hearing in the House Foreign Affairs Committee, which he chairs.
ISIS 'occupies territory the size of Great Britain, holds an estimated $2 billion in assets, and is believed to be the most well-funded terror group in history.' he warned.
