2020 presidential candidates react to San Diego-area synagogue shooting: 'No one should have to worship in fear'

WATCH: 1 dead, 3 injured in synagogue shooting

The news of a deadly shooting in Poway, California, on Saturday brought back memories of several recent attacks on houses of worship, including last weekend in Sri Lanka, last month in Christchurch, New Zealand, and exactly six months prior at a Pittsburgh synagogue.

President Donald Trump reacted both before leaving for a rally in Wisconsin and on Twitter, saying on the White House's South Lawn, "My deepest sympathies go to the people that were affected, the families, their loved ones. By the, obviously, looks right now based on my last conversations, looks like a hate crime. We'll get to the bottom of it."

Trump's comments have drawn some derision for a level of hypocrisy, as he spoke one day prior at a conference for the National Rifle Association.

The suspect in the shooting, 19-year-old John Earnest, said he was not a fan of Trump in online writings.

The nearly 20 Democratic candidates on the campaign trail over the weekend were quick to respond to the shooting, as well.

California Rep. Eric Swalwell was the only one to directly mention Trump, saying in a response to Trump's tweet, "Spare us your thoughts and prayers. It’s an alibi for inaction. You told the NRA yesterday you’d keep dangerous guns in the hands of dangerous people. We will take it from here with action."

Joe Biden, Cory Booker, John Hickenlooper, Amy Klobuchar, Beto O'Rourke and Bernie Sanders did not mention Trump, but did call for better gun control.

The rest of the candidates focused on protecting peoples' rights to practice religion in safety, regardless of the denomination.

Former Vice President Joe Biden

"Jill and I are devastated to hear about today’s shooting at the Chabad Poway synagogue. No one should have to worship in fear. As a country, we must speak out against bigotry and gun violence. We’re in the battle for the soul of this nation—and it’s on all of us to act."

Sen. Cory Booker, D-N.J.

"Praying for comfort and healing for the Chabad of Poway congregation today, as we deal with yet another mass shooting at a house of worship, fueled by anti-Semitism. Gun safety reform needs to happen—now."
