Las Vegas (CNN) - Former Vice President Joe Biden took a swipe Saturday at President Donald Trump as the former vice president rallied Democrats in Las Vegas shortly before the President was set to hold a rally of his own a few hundred miles north of here in Elko.
The round of criticisms offered an early preview of a potential Biden-Trump matchup as the former vice president is mulling a presidential bid in 2020.
In a post-rally interview before boarding Air Force One, Trump said he hopes Democrats nominate Biden.
Biden traveled to Nevada to boost support for Democrats in the state -- including Rep. Jacky Rosen, who is running for the US Senate seat held by Republican Sen. Dean Heller.
While in Nevada, the former vice president also weighed on the homicide of Washington Post columnist Jamal Khashoggi.
The President, in an effort to galvanize voters ahead of next month's midterm elections, held one of his signature Make America Great Again rallies in Elko, Nevada, where he sought to outline the differences between the GOP and Democrats, particularly on the issue of immigration.
Trump also stumped for Nevada Republican Sen. Dean Heller, who is fighting to maintain control of his seat from his Democratic challenger, Rep. Jacky Rosen, whom he called "Wacky Jacky" at the rally as he has done in the past.
At Saturday's rally, the President lampooned political correctness, calling it "a crazy phenomenon that's going on" and expressed regret at how closely his language is watched.
The President's Nevada stop comes fewer than 24 hours after his Arizona rally, where he also spoke at length about Democrats and immigration.
During both his campaign and his White House reign, President Trump has referred to journalists as "disgusting," "crooked," "dangerous," and, most significantly, as "the enemy of the American people." That phrase, closely echoing Josef Stalin's, all but invites the Stalinist solution to such treason: perhaps the show trial, perhaps the Gulag cell, perhaps the executioner's bullet.
While the fatal shooting last summer of five employees, including four journalists, on the Capital Gazette in Annapolis, Md., had no known roots in Trump's rhetoric, other news organizations have received credible threats that do cite or evoke the presidential hatred.
In the old-fashioned world, meaning the one before the Trump presidency, Americans would be right to worry that his feeble response to Jamal Khashoggi's death would embolden autocratic governments or their complicit vigilantes around the world to take similarly brazen action against journalists.
