"Did the president know and when did he know it?" he said.
Spicer's comments were made at a press conference following the sudden resignation of National Security Advisor Michael Flynn.
Leonid Slutsky, chairman of the foreign affairs committee in the lower house of parliament, said that Russia had "decided too soon, for all our unconditional sympathy to President Trump's constructive rhetoric, that he's pro-Russian in some way - he's pro-American".
"He's not out of the woods", said a US official who is familiar with the transcripts of intercepted communications between Flynn and the Russian ambassador to the United States, Sergey Kislyak, in late December.
"It's clear that there are people within the intelligence community that disagree with President Trump, that don't want to see his administration succeed - that's part of the configuration of these timed leaks that [have] come out", Mr. King, Iowa Republican, said on CNN's "New Day". The official said they weren't sure whether the intercepted phone call - where Flynn reportedly talked with the ambassador about sanctions - was based on Federal Bureau of Investigation intelligence or NSA intercepts, or whether the call between Flynn and the Russian Ambassador was collected under a FISA warrant. It's more challenging than simply cherry-picking damaging disclosures about Hillary Clinton from Wikileaks (which Obama warned were provided by hackers with ties to the Russian government, shortly before he left office), which had been the media's obsession throughout much of 2016.
Conway did not say Trump asked for Flynn's resignation.
A Democrat representative has strongly criticised Mike Flynn's reported communication with Russian Federation ahead of Donald Trump's election win describing "conspiring" with Russian Federation as "the definition of treason".
Flynn acknowledged in his resignation letter that he had "inadvertently briefed" Pence and others with "incomplete information" regarding his phone calls with Kislyak in the weeks before Trump assumed power. The scene raised eyebrows among former White House security officials. "Will these leaks be happening as I deal on N.Korea etc?" he wrote.
Trump nominee to head Labor Department drops out
The fast-food CEO contributed large sums of money to both the Trump campaign and the Republican National Committee. The Trump administration has yet to name a new nominee for either position.
"This. Is. Not. Normal", said Democratic Senator Elizabeth Warren, a vocal Trump critic.
President Trump's disgraced former national security adviser, Michael Flynn, will no longer have access to classified material after having his security clearance suspended.
Trump is considering whether to retain Flynn in his White House position.
Top White House officials have been reviewing Flynn's contacts with the Russians and whether he discussed the possibility of lifting USA sanctions on Russia once Trump took office.
Flynn and Kislyak, according to widespread US news accounts, discussed the sanctions Obama imposed on Russian Federation late a year ago.
It is unclear what Mr. Flynn told the Federal Bureau of Investigation agents, or whether his account during the interview was contradicted by intelligence intercepts.
Flynn, a retired U.S. Army lieutenant general, was an early supporter of Trump and shares his interest in shaking up the establishment in Washington. Spicer said the White House concluded it was not a legal issue involving Flynn's contacts with Russian Federation, but rather his misleading assertions to Pence. Spicer said Flynn has not resigned.
The Russian lawmaker believes it is obvious that "Flynn had to resign after facing pressure".
