Trump's rally, hard by the "successful border fence", will be met by the Baby Trump blimp and a galvanized March For Truth and Celebration of El Paso featuring Beto O'Rourke, who often cites the contributions of immigrants to his city.
The former three-term congressman from Texas is joining a one-mile march that will end with O'Rourke giving a speech critical of Trump's push for billions in federal funds to extend a wall along with border with Mexico.
Trump chose El Paso as a historic crossing point where, he says, walls have eradicated an out-of-control influx of criminals from Mexico and made the city a model for what could happen elsewhere on the border.
But as the El Paso Times pointed out, the crime data has not backed this up.
Emiliano Sala: Southampton fan detained after making plane gesture against Cardiff
Ghana striker Abdul Majeed Waris has bid his departed Nantes attacking partner Emiliano Sala . The two Southampton fans are set to be banned from future home games.
But there'll be a counter-message a short distance from where Trump speaks when rising Democratic star Beto O'Rourke - a possible challenger to Trump in 2020 - holds his own rally. Ted Cruz of Texas. In this democracy, he told residents, "We (can) get past the lies and fear, focus on the facts and human lives in our midst, and do the right thing.The eyes of the country are on El Paso, and we're going to tell our story".
He would bring fundraising and grassroots firepower to an already crowded Democratic field hoping to take on Trump in next year's election.
Democrats, who control the House of Representatives, and Trump's Republicans, who control the Senate, reported a setback over the weekend, with both sides haggling over the amount of potential money and what exactly it would be spent on.
In an interview Monday on Fox News, the commissioner of Texas' Department of Agriculture touted the effectiveness of fencing in El Paso, saying that crime dropped significantly in the city. The president has stated he is considering declaring a national emergency to construct the wall without the approval of Congress.
