Democratic presidential candidateis projected to win the Kentucky primary, according to Kentucky Secretary of State Alison Lundergan Grimes.

In an interview with CNN on Tuesday night with 99 percent of the votes counted, Grimes, a Clinton supporter, noted that the vote totals are considered unofficial until the end of May.

“The results tonight that you see from the secretary of state’s office all remain unofficial,” Grimes said. “I do believe though, based on what we’re seeing coming in, that Kentucky will remain in the ‘win’ column for Clinton.”

Grimes was pressed about whether she is declaring Clinton the unofficial winner of the primary.

“That is what it looks like right now,” she said. “We have 99 percent of our precincts reporting based on the unofficial vote totals we are seeing, Hillary Clinton will be the unofficial nominee on behalf of the Democratic Party here in the Commonwealth of Kentucky.”

In a Tweet after Grimes's comments, Clinton declared herself the winner:

We just won Kentucky! Thanks to everyone who turned out. We’re always stronger united. https://t.co/8qYPHIje8I pic.twitter.com/elNUP4nFoO — Hillary Clinton (@HillaryClinton) May 18, 2016

Rep. Sannie Overly, chair of the Kentucky Democratic Party in a statement congratulated Clinton "on an extremely close win here in Kentucky, and we're excited about the energy she and Bernie Sanders have poured into the Commonwealth during the race."

Clinton will win the slight majority of the state’s 55 pledged delegates as she moves closer to clinching the nomination. Polls closed in the state at 7 p.m. but the margin was razor thin and the race was too close to call until after 10 p.m., when Grimes appeared on CNN to discuss the results.
