Two sources with knowledge of the matter first reported Dowd's departure to the New York Times, which was later confirmed by fellow Trump lawyer Jay Sekulow in a statement to Politico.
Attorney John Dowd's departure marks at least the second major reshuffling of Donald Trump's legal team in the previous year. Dowd stirred controversy when he said Mueller's investigation should end, comments he later walked back.
Trump intensified his criticism of Mueller last week, calling the special counsel out by name in a string of Twitter messages.
Days before Dowd's resignation, he released a statement that the Russian Federation investigation should end, but that statement received backlash and stoked turmoil within Trump's legal team, sources told CNN.
DiGenova believes Trump is being "framed" and has frequently called for Federal Bureau of Investigation and Department of Justice officials to be investigated for corrupting the 2016 presidential election. He later clarified that he was speaking for himself, and not in his capacity as the president's lawyer.More news: Osaka cruises past Kasatkina to claim maiden title — WTA Indian Wells
Dowd's resignation and the expectations of a legal-team shakeup indicate Trump is likely to increase his offensive against Mueller and the Russian Federation investigation, which the president has called a "hoax" and a "witch hunt".
His work on behalf of Trump has previously raised eyebrows.
Dowd initial appointment to the team was striking for his reputation as a legal brawler who once led Major League Baseball's investigation into all-time hit king Pete Rose. DiGenova was expected to play a forward-facing role on the legal team, filling what Trump felt was a lack of voices publicly defending him and challenging the special counsel.
"In response to media speculation and related questions being posed to the administration, the White House yet again confirms that the president is not considering or discussing the firing of the Special Counsel, Robert Mueller", Trump attorney Ty Cobb said Sunday. Dowd and Trump clashed on legal strategy in recent weeks, according to the Washington Post, though the paper did not specify the disagreement.
