So what the heck was Joe Biden lying about the other day ? Zero evidence that refugees are more violent ? Maybe when compared to non refugee Muslim immigrants.
He’s a liberal and the all lie, because it comes natural to them and they can’t help it.
Without access to more data, it's difficult to pronounce this true or false. The article does say:
For the period September 2001 through 2014, data shows the U.S. successfully prosecuted 580 individuals for terrorism and terror-related cases. Further, since early 2014, at least 131 individuals were identified as being implicated in terror.
Across both those groups, the senators reported that at least 40 people initially admitted to the U.S. as refugees later were convicted or implicated in terror cases.
Among the 580 convicted, they said, at least 380 were foreign-born. The top countries of origin were Pakistan, Lebanon and Somalia, as well as the Palestinian territories.
The 380 foreign-born convicts heavily over-represent the Middle East. But, apparently only about 10% were considered "refugees".
This is why parsing the sentence carefully is necessary. If you confine the discussion to "refugees", the results are much different than considering all immigrants from majority Islamic countries.
