The Donald Trump transition, already off to slow start, bogged down further Tuesday with the abrupt resignation of former Congressman Mike Rogers, who had been coordinating its national security efforts.
Two sources close to Rogers said he had been the victim of what one called a "Stalinesque purge," from the transition of people close to New Jersey Gov. Chris Christie, who left Friday. It was unclear which other aides close to Christie had also been forced out.
The Trump transition did not immediately respond to a request for comment.
Rogers confirmed his exit in a statement that said that, despite his departure, he planned to continue to "provide advice and counsel as needed to the incoming Trump administration."

He and his top aide had been working for months, preparing the groundwork for transition. Two sources close to the situation described an atmosphere of sniping and backbiting as Trump loyalists position themselves for key jobs.
"It was a privilege to prepare and advise the policy, personnel and agency action teams on all aspects of the national security portfolio during the initial pre-election planning phase. Our work will provide a strong foundation for the new transition team leadership as they move into the post-election phase, which naturally is incorporating the campaign team in New York who drove President-elect Trump to an incredible victory last Tuesday," Rogers said in the statement.
