Meanwhile, President Donald Trump told the New York Times on Wednesday that Rice may have committed a crime.
Rice said she would need to see unmasked names as part of her to "protect the American people and the security of our country", Rice said Tuesday.
Former Obama National Security Advisor Susan Rice admits it's common to ask for the identities of Americans caught up in surveillance.
It was reported this week that Rice, in her role as national security adviser, asked intelligence agencies to "unmask" the names of Trump associates mentioned in reports of surveillance activities. USA officials may request-but not order-Americans' names unmasked for a few select reasons. USA intelligence agencies routinely do legal surveillance of foreign nationals thanks to a section of law in the "Foreign Intelligence Surveillance Act", generally referred to as FISA. What we're seeing here is USA officials doing jobs to respond to what had markers of a counterintelligence threat: "the Trump campaign".
President Donald Trump one month and one day ago accused former President Barack Obama of committing a felony, wiretapping him in Trump Tower.
Therefore, "contrary to Susan Rice's latest version of events", her actions have "little or nothing to do with whether laws were broken", Mr. McCarthy concluded. If the National Security Agency deems those reasons vaild, it will unmask the names. He called Bannon "the leading anti-China voice in the White House" and said he believed that made the Chinese "uneasy".More news: Markets Right Now: Stocks move higher at midday
The unmasking review was led by Ezra Cohen-Watnick, the NSC's senior director of intelligence.
"The pattern of Rice's requests was discovered in a National Security Council review of the government's policy on "unmasking". individuals in the US who are not targets of electronic eavesdropping, but whose communications are collected incidentally", Lake wrote.
Trump criticised media outlets, including The New York Times, for failing to adequately cover the Rice controversy - while singling out Fox News and the host Bill O'Reilly for praise, despite reports this week that the veteran conservative commentator settled five lawsuits filed by women claiming sexual harassment or inappropriate behaviour.
Rice was routinely briefed on intelligence that was collected and then deemed relevant by USA spy agencies. "I never have and never will". It is unclear why these intelligence intercepts were considered so important that they would need to be shared with the president's national security adviser.
Leaking classified information could be a crime but no evidence has surfaced publicly indicating Rice did that and she flatly denied doing so in her interview with MSNBC.
