Chairman Trey Gowdy announced the House Select Committee on Benghazi is "finally" slated to interview top aides to Hillary Clinton about their role in the State Department's handling of the 2012 terror attack.

Among them are Cheryl Mills, Clinton's chief of staff, Huma Abedin, her deputy, and Jake Sullivan, director of policy planning at State.

The South Carolina Republican blasted the committee's ranking Democrat, Rep. Elijah Cummings, for a letter sent earlier Monday in which the Maryland Democrat had complained that an anonymous source had "doctored" an email exchange when describing it to a reporter last month.

Gowdy highlighted the fact that Clinton edited some of the email exchanges she submitted to the State Department and withheld the entirety of others, suggesting the gaps in published exchanges created by such interference could "lead an observer to confuse" conversations like the one that was leaked to the reporter.

"Several of Secretary Clinton's earlier representations appear to be factually deficient including, but perhaps not limited to, her representation that she turned over her complete record as secretary of state, that she used a single device for 'convenience' and that there was no classified information in her emails on her server," Gowdy wrote to Cummings Monday.

The chairman questioned the Democrats' decision to spend a "healthy portion" of a closed-door deposition last month "apologizing" to former Clinton aide Sidney Blumenthal, a divisive political operative who evidently served as an off-the-books advisor to Clinton at State.

Committee Democrats have called on Gowdy to release a transcript of the Blumenthal deposition in order to provide context to a cache of his emails published by the committee last month.

The Republicans have countered that doing so may discourage future witnesses from being candid behind closed doors, arguing that the select committee would be treating Blumenthal differently than every other witness by publicizing his deposition.

Gowdy called Cummings' claim that a Republican source had twisted a Clinton email exchange for the benefit of a news article a "breathless accusation," noting that the story in question was quickly updated to reflect the true nature of the correspondence.

He instead pushed the ranking member to join calls for Clinton "to relinquish her server to a neutral, detached third party for review to make sure the public record is intact."

After weeks of bitter public exchanges over where to steer the congressional probe, Gowdy vowed to end his bickering with Cummings.

"I have instructed my staff to no longer waste time responding to your increasingly wild, inaccurate and baseless claims and to instead remain focused on discharging the mission given to us by the House of Representatives," Gowdy wrote.

The two clashed last week over an unscheduled vote on whether to publish the Blumenthal transcript.

The Clinton campaign has attempted to downplay the select committee's findings by calling the investigation a "political charade" in a video emailed to supporters last week.

Gowdy has long argued that the State Department's reluctance to cooperate with congressional document requests has slowed the pace of the probe significantly. He said Monday the interviews with Mills, Abedin and Sullivan would be "challenging" given the agency's refusal to turn over all of the three aides' emails.
