2020 candidates respond to El Paso, Texas, shooting

New Jersey Sen. Cory Booker and Montana Gov. Steve Bullock reacted early to the shooting situation in El Paso, Texas, as information emerged Saturday afternoon.

At a public union forum in Las Vegas, Booker told reporters that he didn’t have a lot of the details yet.

But he began to passionately advocate for people to join together for a “movement” now — and not to wait for Election Day — to act on passing gun reforms “before it happens to yet another community, before another person dies.”

“I just want to say we are in this unimaginably just distraught moment in this country where we seem to be almost accepting this idea that these are going to be a regular occurrence,” Booker said. “And so I have had enough of this, especially living in a community where gun shots are all too regular.”

“We have to, in this election, have leaders who are willing to stand up and say I'm not going to let this issue be determined by what the interests of the corporate gun lobby are,” Booker said.

Booker later posted to Twitter, "Enough. We need to end this national nightmare."

Bullock said “my (heart goes) out to the folks in Texas.”

“I think if we could ever look at this as a public health issue — not just a political issue — we could make meaningful progress,” Bullock said.

Former San Antonio Mayor Julián Castro took to Twitter to call the shooting, "truly devastating" and asked for people to "stay safe."

Democratic presidential candidate Marianne Williamson, a spiritual book author and native of Houston, offered prayers for the inhabitants of El Paso, as well as prayers "for all the rest of us as well, that we might summon up the courage to remove this scourge from our midst."

Democratic presidential hopeful and South Bend, Indiana, Mayor Pete Buttigieg tweeted, "My grandmother used to take me to Cielo Vista Mall. Now it’s one more mass shooting scene. How many more must grieve before we act?

Texas Sen. Ted Cruz also addressed the shooting, tweeting, "My heart is with everyone in El Paso struck by this unspeakable evil. Heidi & I are praying for the victims & their families & are grateful for the first responders, local authorities & law enforcement working tirelessly to bring the perpetrator of this depraved act to justice."

"There are millions of people in Texas and across the country standing behind you," he added.

Nearby businesses are on lockdown

At least three businesses in the area are on lockdown.

Three Walmart employees took refuge at a Landry's Seafood house, restaurant manager Oscar Collazo told CNN. He said the women appeared "shook up" but not injured.

Landry's had already gone on lockdown, Collazo said, but opened its doors when the Walmart employees ran there.

"We never thought it would be so close to us this time," he said. "You see on the news all the time, but you don't think it could happen here until it does."

The nearby Hooters and Red Lobster are also on lockdown. Employees at those restaurants told CNN they are safe and see a lot of police, helicopters and people running around outside.
