Former Secretary of State Hillary Clinton's campaign was accused of election fraud during Kentucky's presidential primary last week — and now officials are going to take a second look at the results.

Vermont Sen. Bernie Sanders' presidential campaign requested a statewide recanvass in Kentucky's presidential primary Tuesday, where he trails Clinton by less than one-half of 1 percent of the vote — less than 2,000 votes.

The formal request will trigger a statewide investigation into the election results, a move Saunders supporters say is long overdue after over 76 complaints of election fraud came out of the Bluegrass State's Democratic primary.

The Sanders campaign said it has asked the Kentucky secretary of state to have election officials review electronic voting machines and absentee ballots from last week's primary in each of the state's 120 counties to make sure votes aren't missing.

Sanders signed a letter Tuesday morning requesting a full and complete check and recanvass of the election results in Kentucky.

Should the recanvass uncover evidence of widespread election fraud, it would likely trigger further investigations.

"Politically, [the request] gives Sanders the opportunity to continue to call into question the results; allow some of his supporters to continue to allege that Secretary of State Alison Lundergan Grimes, who is close to the Clintons, put her finger on the scale; raise money — and do all of it at no cost," NPR reports.

The office of Kentucky's secretary of state said Tuesday that they will begin the process on Thursday.

"He's in this until every last vote is counted and he's fighting for every last delegate," said Sanders' spokesman Michael Briggs.

Clinton holds 1,924-vote lead over Sanders out of 454,573 votes cast. The Associated Press had not called the race, despite Clinton's slight lead, in the event that Sanders might ask to recanvass the vote.

A recanvass is a review of the voting totals, and is paid for by the state of Kentucky. Sanders can ask a judge to order a recount or an examination of individual ballots but his campaign would have to pay for it, and Sanders has blown through just about all his cash on hand despite his campaign having raised more money than any other presidential candidate.
