Dubke, who was brought into the White House in March as head of the office that runs press and other public relations issues, wanted to stay on through Trump's first foreign trip to ensure a smooth transition, Conway said. Though many people are speculating that he quit over the mishandling of the Russian investigation fallout, it has been reported that he is leaving "for personal reasons." .
Communications director Mike Dubke has resigned, and the White House is considering holding fewer on-camera briefings and having other senior aides step in to help Spicer at the podium more frequently.
Other potential changes to the White House communications office are also expected, according to USA media, including fewer on-camera briefings with Spicer.
The Republican president came home to face more questions on Russian Federation after media reports about communications during and after the campaign between his son-in-law and close adviser, Jared Kushner, and Russia's ambassador to Washington.

The Communications Director at the White House is responsible for developing and promoting the president's agenda of the President and leading the media campaign of the White House.
In past years, the White House has not treated the first day of June or December as a sacrosanct deadline - the matter was dealt with on the second day of June in 2014, and the third in 2015. Mr Dubke "offered to remain onboard until a transition is concluded", Mr Priebus said.
Trump was "frustrated across the board" with his communications team, especially over anonymous leaks to the media, the sources said. Dubke founded Crossroads Media, a GOP firm that specializes in political advertising.
On "Fox & Friends" this morning, David Bossie, who served as Trump's deputy campaign manager, said the media is out to "destroy" the president.
The White House press secretary also said the Afghan strategy review is still underway.
Mr Spicer, who has garnered a reputation for delivering frosty responses to questions from the press corps, came back to his role in typically belligerent fashion - blasting a BBC journalist for a false tweet about US President Donald Trump.
