The head of the US Senate Intelligence Committee has accused the CIA of spying on Congress. Dianne Feinstein said the CIA had inappropriately searched the computers of congressional stuff who were investigating allegations that it had tortured suspects during the Bush administration. Senator Feinstein said the agency had obstructed the investigation, lied about its activities and electronically removed files from the Committee's computers. She said it was a serious matter.

“I have grave concerns that the CIA search may well have violated the separation of powers principles, embodied in the United States constitution. It may have undermined the constitutional framework, essential to effective congressional oversight.”

The CIA director John Brennan dismissed the allegations, saying they were completely untrue.

“As far as the allegations of, you know, CIA hacked into you know, senators' computers,nothing can be further from the truth, and we wouldn't do that. I mean, that's just beyond the scope of reason.”

The BBC Washington correspondent says it's following the revelations by the former CIA employee Edward Snowden. The affair will do nothing to reassure Americans about the reach of their intelligence services.
