LOS ANGELES (AP) — The latest on the Democratic presidential primary and Super Tuesday (all times local):

9:10 a.m.

Deadly tornadoes have affected Super Tuesday voting in two southern states.

The Tennessee Democratic Party is moving some polling places damaged by deadly tornadoes that rolled through the Nashville area Monday night. The party on twitter says that voters assigned to 18 polling locations can vote at a designated high school, church and community center.

Tornadoes ripped across Tennessee early Tuesday, shredding at least 40 buildings and killing at least seven people. One of the twisters caused severe damage in downtown Nashville. Police said officers and fire crews were responding to about 40 building collapses around the city.

In Alabama, seven poll workers were getting ready to open the doors to voters at the Lawley Senior Activity Center southwest of Birmingham when cellphone alerts began going off with a tornado warning about 6:45 a.m. Tuesday, said volunteer Gwen Thompson.

She said they went into the bathroom and were OK, but trees were down. The storm knocked out electricity, Thompson said, but the precinct’s two electronic voting machines had battery backups and a few people had cast ballots less than an hour later.

“We’ve voting by flashlight,” Thompson said. (edited)

The early-morning storms in Alabama damaged homes and toppled trees. Winds as strong as 60 mph (97 kph) were reported by the National Weather Service. Tornado warnings issued in at least five counties.

A super PAC supporting Joe Biden‘s presidential bid is running a robocall in some Super Tuesday states featuring positive words about Biden from former President Barack Obama.

Amanda Loveday of Unite the Country PAC says the call is running through Tuesday in Alabama, Arkansas, North Carolina, Texas and Virginia.

The call features audio from a speech in which Obama calls Biden “a statesman, leader who sees clearly the challenges facing America in a changing world.”

Obama has said he would not endorse a candidate in the Democratic primary, and Loveday says the group used the audio the same as would be done in a traditional campaign ad. She says the group did not need permission to use the audio, nor did it seek permission.

A spokeswoman for Obama said the robocall from Biden's super PAC did not amount to an endorsement and the former president's office was not aware that the group planned to use the old audio.

Several candidates in the race have run television ads featuring positive sentiments from Obama, although he has endorsed no one.

Fourteen states vote in Tuesday’s primary. Loveday said the call also ran in South Carolina before its primary last Saturday and could be used in other states that vote in the future.
