Hillary Clinton's email woes are reaching new heights just a few weeks before the Democratic national convention.

From the release of a scathing report on Benghazi, to a dust-up over her husband's private meeting with the attorney general, to Saturday's news that she was interviewed for several hours by FBI investigators, Clinton stumbled through a difficult week by remaining largely silent.

But her highest hurdles may still lie ahead as the Justice Department prepares to issue a decision on whether the presumptive Democratic nominee will face criminal charges for her mishandling of sensitive material in an unclassified environment.

Clinton's credibility has been called into question over the past month as Freedom of Information Act productions have turned up emails and meetings she did not disclose to the State Department.

The former secretary of state has repeatedly assured voters she turned over all work-related materials to the agency in late 2014. She even signed an affidavit in August 2015 swearing as much to a federal court.

However, dozens of emails have surfaced that were not included in the 30,000 records she provided to the State Department, including several discussing her fear that her private inbox could become "accessible" if revealed to the government.

The FBI is expected to reach a conclusion in the coming weeks. Several of Clinton's top aides have already been questioned by agents on the case, and Clinton herself was interviewed Saturday.

Clinton's interview is seen as one of the final steps in the year-long probe.

While Attorney General Loretta Lynch has given no public indication of where the FBI stands on the investigation, she has pledged to accept whatever actions the law enforcement agency recommends.

Lynch acknowledged Friday that her secret meeting with the spouse of an individual under FBI investigation had "cast a shadow" over how the public perceived the case.

Critics were already skeptical of the administration's ability to remain impartial when looking into the actions of a former cabinet member and present party standard-bearer.

Republicans had pushed for the appointment of an independent counsel in the case since September of last year, citing the fact that Lynch was named a U.S. attorney by President Bill Clinton in 1999 as evidence of a potentially conflicting professional relationship with the Clinton family.

Donald Trump wasted no time capitalizing on the meeting between Bill Clinton and Lynch, calling their visit a "sneak" that was "horrible" for his likely election opponent.
