Lawyers say NSA eavesdropping on U.S. citizen may have led to strike

WASHINGTON (Reuters) - U.S. intelligence officials may have used National Security Agency data collected by eavesdropping on U.S. citizens or residents to target a Somali militant leader in a lethal missile strike, defence lawyers in a California terrorism-funding case said.

Questions about whether the data may have been collected illegally could fuel fresh controversy over NSA spying on U.S. citizens and residents and the way data it collects is used. Defence lawyers assert there may be legal grounds for a new trial for four men convicted in the case.
