2020 Democrats drive the national conversation after mass shootings

• Sen. Kamala Harris told reporters before attending services at a black church in Las Vegas: "We have a president of the United States who has chosen to use his words in a way that have been about sowing hate and division."
• Sen. Bernie Sanders opened a town hall with a moment of silence and by calling for universal background checks for firearms purchases and more restrictions on assault weapons.
• Sen. Elizabeth Warren, on MSNBC, was among the candidates who called for Senate Majority Leader McConnell to bring senators back to "vote within 48 hours on the two background check bills that have already passed the House."

P.S. Beto gets hot .... Beto O’Rourke, after an emotional vigil in El Paso, asked if there’s anything Trump can do now to make this better (as reported by CNN's Eric Bradner):

• "What do you think? You know the s--- he’s been saying. He’s been calling Mexican immigrants rapists and criminals. I don’t know, like, members of the press, what the f---?"
• Beto later tweeted: "We know what Trump is doing. He stokes racism. He incites violence. We shouldn’t be asking if there’s anything he can do or if he’s responsible for this when we know the answer. I stand by what I said."
