At least 25 people were killed and many others injured after tornadoes ripped through Tennessee early Tuesday -- the same day the state was voting in the Super Tuesday Democratic primaries.
Tennessee Gov. Bill Lee confirmed the death toll at a press briefing in Nashville, saying that the deaths were recorded in four counties across the southeastern state.
"There are still people that are unaccounted for ... search and rescue continues there," Lee said in the afternoon briefing.
The governor had earlier said on Twitter that the state "will continue deploying search and rescue teams, opening shelters across the state, and sending emergency personnel to our communities hit hardest."
The severe weather caused extensive damage, destroying homes, businesses and plane hangars and littering roads with overturned vehicles, according to WKRN.
The tornadoes also left tens of thousands of residents without power.
Tennessee was one of 14 states to vote in the Democratic primaries on Tuesday, and state officials were scrambling to ensure residents could get to the polls after the storm, NBC reported.
The Tennessee Democratic Party (TNDP) on Tuesday afternoon said a judge ruled that all polling sites in Nashville would remain open until 8 p.m., a one-hour extension, and five sites would remain open until 10 p.m., a three-hour extension.
The ruling came following a lawsuit by the TNDP, the party said in a tweet.
President Donald Trump said he was planning to visit Tennessee on Friday "in the wake of the horrible, very vicious tornado."
