• e-mail

Departing White House Communications Director Hope Hicks told lawmakers last week that one of her email accounts had been hacked, according to NBC News. 

Hicks, who announced her resignation last Thursday, had voluntarily appeared the day before to answer nine hours-worth of questions from members of the House Intelligence Committee. 

When answering questions posed to her by Rep. Jim Himes, a Democrat from Connecticut, Hicks said she no longer had access to two of her email accounts – one personal and one campaign – noting that one had been hacked, according to two of NBC's sources.

It was unclear which of of Hicks' accounts had been breached. 

The hack raises questions about who might have tried to access the aide's account and what information her emails may have contained.

Hicks didn't specify when the hack happened, though a number of Hillary Clinton's aides had their email accounts targeted through the course of the 2016 election.

The most famous breaches were that of the Democratic National Committee and Clinton Campaign Chairman John Podesta. 

As for Hicks, she is one of the president's longest-servingpolitical aides, having worked for Ivanka Trump's brand before transitioning to Trump's campaign at its beginning, serving as his press secretary despite never having worked in politics.

Special Counsel Robert Mueller, who is heading a separate Russia investigation from the House Intelligence Committee's on Capitol Hill, has been interested in correspondence, including emails, between Trump aides. 

In a subpoena given to ex-campaign aide Sam Nunberg, who handed it over to the media during his bevvy of interviews on Monday, the special counsel requested correspondence Nunberg had with a number of campaign associates. 

Hicks was on that list, along with eight other campaign aides, as well as the president himself.

Nunberg, who first said he planned to defy the subpoena, now says he will cooperate with the Mueller probe. 

Next up at bat at the House Intelligence Committee is Trump's original campaign manager Corey Lewandowski. 

Lewandowski is slated to speak to the panel's lawmakers on Thursday.
