Dubke only took the communications director job in February, helping relieve White House Press Secretary Sean Spicer, who had initially shouldered the dual burden of crafting the administration's message and delivering that message at press briefings.
They're often officials within the White House or some other part of government who aren't permitted to speak on the record and could face consequences for doing so, but feel the need to share information with the public via the press. Spicer discussed ongoing possible connections to Jared Kushner and Russians as well as the president's global trip.
US news accounts in recent days say Trump has grown increasingly frustrated that reports of the Russian probes are consuming the White House and his attempts to reform the national health care insurance law championed by his predecessor, former President Barack Obama, cut taxes, and change immigration policies.
Returning to Washington, Mr Trump has been faced with new allegations that his campaign may have colluded with Moscow before the election, as his son-in-law and close adviser Jared Kushner's Russian Federation contacts came under scrutiny.
White House counselor Kellyanne Conway also talked about Dubke's departure Tuesday on "Fox & Friends".
In spite of the Trump administration's efforts to discredit the use of unnamed sources, it's been a common aspect of reporting for a long time.
If Trump didn't know anything about what Kushner was doing, it would be to his benefit to say exactly that. "In terms of 'staff shakeups, ' I always read things that simply aren't true". The New York Times first reported the meeting between Kushner and Gorkov in March, but the White House at the time did not explain its aim. He's always proven that - that he is the best messenger not just for what he wants to articulate, but that the American people resoundingly chose him as their president because he understands the frustrations and concerns and values of the American people, and he is probably the best person to communicate that.
Lewandowski and Bossie were seen leaving the White House on Monday.
The Reuters news agency cited Trump administration officials as saying the president plans to bring in his former campaign manager.
Republican and Democratic operatives in recent days have said the problem with a West Wing makeover will be finding qualified and capable Republican hands who are willing to work for a president and administration that are under federal and congressional investigation - and that have struggled to produce clear domestic victories while also angering longtime USA allies like Germany. More attorneys with deep experience in Washington investigations are expected to be added in the weeks ahead.
Meanwhile, the investigation into the president's son-in-law and advisor, Jared Kushner, continues.
