Schiff also had a brief but "cordial" meeting with Trump during his time at the White House, a spokesman said. "If you're asking me, 'Is it appropriate for a member of Congress to come over here?' As Chairman Nunes said, he wasn't hiding or roaming".
Nunes sparked a controversy last week when he said he received information from an undisclosed source at the White House that conversations by President Donald Trump and his staff had been swept up as "incidental collection" by US spy agencies targeting foreign agents.
Members of the House intelligence committee say, meanwhile, that they are still waiting to review the information Nunes reviewed.
Team Trump may have managed to navigate the politics of 2016, but the maze of the vast federal bureaucracy Steve Bannon seeks to "deconstruct" might be the ultimate undoing of Trump's White House.
In response to a question from The New York Times' Glenn Thrush about vague allegations regarding Clinton's relationship with Russia, Spicer attempted to argue that the former secretary of state's Russian connections are more suspicious than Trump's.
"I can say that we've continued to say the substance of this matter and what continues to come to light in terms of Obama officials admitting either off the record or, frankly, on the record, consistent with what Dr. Farkas says, that there was clearly an attempt to do something politically motivated with the intelligence out there", he said.
South Korea's ousted leader Park Geun-Hye arrested
State prosecutors have up to 20 days to level formal charges against Park in order to keep her in detention awaiting trial. Park has said she only let Choi edit some of her presidential speeches and got her help on "public relations" issues.
"You're playing cute there", Spicer exclaimed.
"There is still much work and many more witnesses and documents to obtain before any immunity request from any witness can be considered", Rep. Adam Schiff, the House Intelligence Committee's ranking Democrat, said in a statement.
Nunes' sources have since been revealed to be Ezra Cohen-Watnick, the senior director for intelligence for the White House National Security Council, and Michael Ellis, a lawyer for the White House and former aide to the House Intelligence Committee. "And fourth and finally, I want to be clear, none of this surveillance was related to Russia, or the investigation of Russian activities or of the Trump team", he added.
The Senate and House intel committees are investigating Russian involvement in last year's presidential election.
"These people wrote this not for the Obama administration but for the American government, with full knowledge that whatever they were writing would be accessible by the president-elect or the president", Hayden said.
Rep. Devin Nunes (R-CA) now under left-media and Democrat fire for seeing the information, but not sharing it with his committee, now knows who the individual is, according to the reports. Spicer insisted Hillary Clinton had far more ties to Russian Federation, and chided the White House press for not being all over that one. For fear that naming names could cause a "chilling effect" on others coming to the committee with sensitive info, Nunes has only described his sources as "whistleblowers" putting themselves at risk to expose wrongdoing. It has not yet been confirmed whether or not the Obama administration was tied to this possible surveillance. Former Obama officials contend that intelligence was disseminated to pockets of the government where officials had clearance to see classified reports, not publicly leaked.
