President Donald Trump’s communications director Mike Dubke confirmed Tuesday morning that he is leaving the White House after barely three months working in the tumultuous and truth-starved administration.

Axios, which first reported Dubke had quit, said his “departure is a reminder of how hard it is for newcomers to thrive in Trumpland.” According to Axios, Dubke submitted his resignation on May 18, but agreed to stay until Trump returned from an overseas trip. Reports indicate Tuesday could be his last day, but the White House has yet to make an official announcement.

In confirming his early departure, Dubke told Politico the reasons were “personal,” but showered praise on his fellow White House staffers and his time working for Trump.

Though Dubke played a much less public role than figures like Press secretary Sean Spicer and top spokesperson KellyAnn Conway, Dubke’s resignation speaks directly to speculation in recent weeks that the communications team was under strain and headed for a shakeup.
