"I inadvertently briefed the Vice President-elect and others with incomplete information regarding my phone calls with the Russian ambassador".
'I have sincerely apologized to the President and the Vice President, and they have accepted my apology'. The post is being filled in the interim by Lt. Gen. Joseph Keith Kellogg, chief of staff for the National Security Council.
Pence, relying on information from Flynn, publicly vouched that the retired Army lieutenant general did not discuss USA sanctions against Russian Federation in calls late a year ago.
Spicer said that Flynn communicating with Kislyak, or any other foreign counterpart, even before he took office, is part of the national security adviser's job in preparing for the transition of power.
Flynn resigned Monday night following reports that he had discussed USA sanctions with Russian Federation prior to Trump's inauguration - and then misled Vice President Pence about that conversation. Chris Christie on Wednesday defended President Donald Trump's administration after Michael Flynn resigned as Trump's national security adviser following reports that he misled Vice President Mike Pence about his contacts with Russian Federation. Possible replacements reportedly include former CIA Director David Petraeus and Vice Admiral Robert Harward, a retired US Navy SEAL, a senior administration official said.
The controversy comes as Mr Trump and his leading advisers seek to steady the White House after a rocky start.
"I'm actually having a really good time", Mr. Trump said at one point.
The news comes after an earlier report that Flynn may be susceptible to Russian blackmail, according to an assessment from the Department of Justice that was compiled late last month.
Over the weekend, Mr Trump told associates he was troubled by the situation, but did not say whether he planned to ask Mr Flynn to step down, according to a person who spoke with him recently.
"I would like an independent commission to be able to vet any information to decide whether it's suitable for public disclosure", he said.
In its infancy, the Trump administration is reeling over the forced resignation of national security adviser Michael Flynn after it was revealed he attempted to cover up conversations he had with the Russian ambassador.
Spicer, Feb. 14: We've been reviewing and evaluating this issue with respect to General Flynn on a daily basis for a few weeks, trying to ascertain the truth.
'Matt, I'm telling you what the president has said, ' Conway replied.
"Sounds like he did the right thing, he didn't want to be a distraction", Chaffetz said of Flynn. "After the White House was informed, who made the decision to allow Flynn to continue to serve despite the fact he misled the administration?"
