The departure of Michael Dubke, Mr Trump's communications director, comes as aides say the president has grown increasingly frustrated by allegations of Russian meddling in the 2016 election and revelations of possible ties between his campaign and Moscow.
"What your question assumes is a lot of facts that are not substantiated by anything but anonymous sources that are, so far, being leaked out", Spicer said.
Asked about reports that U.S. President Donald Trump's son-in-law had tried to set up a clandestine communication channel with Russian Federation before the president took office, U.S. National Security Advisor H.R. McMaster said Saturday that so-called "back-channeling" was normal.
"We have back-channel communications with any number of individual [countries]".
White House spokesman Sean Spicer abruptly walked out of his press briefing Tuesday as journalists shouted questions after him, highlighting the increasingly adversarial relationship between the Trump administration and the reporters who cover it.
Lewandowski tells "Fox & Friends" that he wants to help promote Trump's agenda whether he's inside the White House or not.

As the days and weeks go by it is becoming evident that the Russia-Trump conspiracy theory is and will forever remain just that-a conspiracy theory.
WASHINGTON-What did the president know about Senior White House Adviser Jared Kushner's alleged attempt to set up a backchannel with Russian Federation and when did he know it?
Yet Kushner remains. And no communications strategy, however brilliant, has a chance of succeeding so long as Trump has access to his Twitter account. After all, it's worth emphasizing that The New York Times and The Washington Post continue to depend upon anonymous sources, and the Times couldn't confirm the Post's report.
"It's one of many worrisome bits of evidence, that collectively raise a cloud of suspicion over whether there are any improper contacts between the Trump business, the Trump family, Trump himself and Russian Federation", said Whitehouse.
President Donald Trump has renewed his criticism of Germany following Chancellor Angela Merkel's suggestion that her country needs to adopt a more independent stance in world affairs.
