US Congress to extend surveillance tactics, aide says

WASHINGTON - US congressional leaders have struck a deal to extend key anti-terrorism surveillance tactics for four years, a senior Democratic aide said on Thursday, a move that would avoid a potentially contentious fight over the tactics.
The three tactics, initially approved by Congress in the wake of the Sept. 11, 2001 attacks, were set to expire later this month. Under the deal struck they will be extended until June 1, 2015, according to the aide, who declined to be further identified.
The tactics include roving wiretaps on terrorism suspects who change modes of communications, tracking foreigners who may have loose ties to militants but are acting as "lone wolves" in plotting attacks, and accessing certain business records.
