Is an apology from CIA Director John Brennan enough after revelations that the agency spied on U.S. Senate computers?

Brennan made the admission last week after an internal probe showed that CIA employees in the Executive Branch improperly spied on the Legislative Branch by searching Senate computers and reading staffers' emails earlier this year. Now, there are calls from the Senate for Brennan to resign.

Judge Andrew Napolitano reacted this morning, explaining that the CIA works for the president and can "spy, lie, steal, even fight secret wars" as long as the agency reveals it all to the House and Senate Intelligence Committees.

"When it lies to the people to whom it reports, who are essentially its regulators: A, it commits a crime and, B, it loses the authority to do the things that the president wants it to do," said Napolitano.

In March, Brennan stated that people who accuse the CIA of "tremendous monitoring and spying and hacking will be proved wrong." The judge said Brennan's admission is "unprecedented" and CIA agents spying on the Senate is a "per se" violation of the Constitution.

Napolitano said Brennan could be indicted if he lied to the Intelligence Committees in classified briefings. On Friday, President Obama expressed "full confidence" in Brennan, saying the CIA showed "very poor judgment" and pointed out that Brennan was the one who called for an Inspector General report on the matter.

The judge said if Obama did not know about the CIA spying he was "out to lunch" and if he did know about it and allowed it, then he has "probably committed an impeachable offense."

Obama also mentioned harsh interrogations of terror suspects during the Bush administration, saying "we tortured some folks." Napolitano slammed the president for making all of these statements on a "sleepy, lazy Friday afternoon" when the public was probably not paying attention.

"The language you just heard from the President of the United States as he attempted to justify [the CIA's actions] is enough to make George Orwell blush. ... The government is out of control. The president is permitting spying on the Senate. And these guys can't keep their jobs when they lie," he argued.
