In a statement, Dubke says: "It has been my great honour to serve President Trump and this administration. It has also been my distinct pleasure to work side-by-side, day-by-day with the staff of the communications and press departments."
A Republican consultant, Dubke joined the White House team in February after campaign aide Jason Miller Trump's original choice for communications director withdrew from consideration. Dubke founded Crossroads Media, a GOP firm that specialises in political advertising.
Kellyanne Conway, White House counsellor, has told The Associated Press that Dubke handed in his resignation before President Donald Trump left for his international trip earlier this month.
In an interview on Fox News today, Conway said Dubke "made very clear that he would see through the president's international trip, and come to work every day and work hard even through that trip because there was much to do here back at the White House.
