Meanwhile, the president's top lawyer has invited Republican and Democratic lawmakers to view classified information at the White House.
Rep. Adam Schiff said the White House has not explained why the materials were shared with only one member of the committee, chairman Devin Nunes. A senior White House official said that Trump spoke with Schiff for 10 minutes after the Democrat viewed the materials for a couple hours Friday, describing their meeting as "very cordial and polite".
"So, first, I recently confirmed that on numerous occasions the intelligence community incidentally collected information about USA citizens involved in the Trump transition", Nunes said.
Later in the answer, he said the White House was concerned with both.
Nunes' visit to the White House almost stalled the committee's investigation into alleged contacts between Trump associates and Russian Federation during the election. Elijah Cummings (D-Md.) asked whether the pair are "personally aware of the activities of your own staff" surrounding Nunes' visit to the White House last week.
"Later in March, in the ordinary course of their work, NSC - National Security Council staff discovered information that may support the questions raised by the president and Dr. Farkas's claim".
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.
Trump will seek to rebuild the US relationship with Egypt at a meeting on Monday with Egyptian President Abdel Fattah al-Sisi focused on security issues and military aid, a senior White House official says.

Instead, in just 24 hours, what the administration repeatedly tried to dismiss as a "hoax" has gathered fresh momentum, raising the stakes for the ongoing investigation into whether the Trump campaign coordinated with Russian intelligence operatives to tilt the 2016 USA election in his favor. Schiff called for the full contents of the documents to be shared with all members of both the House and Senate Intelligence Committees.
On Thursday, however, reports surfaced that three White House officials had helped provide the intelligence documents to Nunes.
JULIAN ZELIZER: The John Dean testimony was certainly one of the most shocking parts of the hearings for many Americans when they heard someone from within the administration speak poorly about the administration and confirm some of the worst fears that people had.
One problem: Farkas left the Obama administration in 2015.
"We're not going to get into sources and methods". Spicer insisted Hillary Clinton had far more ties to Russian Federation, and chided the White House press for not being all over that one. A man shouted through a megaphone: "Come out and play, Nunes, you coward".
Earlier this week, Nunes was asked by reporters if he would continue leading the investigation into Russian meddling in the election.
