"With the president being in El Paso, it provides an opportunity to test a message that's very different than President Trump's message", communications consultant Hector Nieto said.
"He's making an effort to use this community as a prop to make his case for a border wall", O'Rourke said.
O'Rourke and his allies are hoping to display "the reality of the border - a vibrant, safe, binational community that proudly celebrates its culture, history, diversity and status as a city of immigrants".
"If people had contacted me about our attorney general's remarks, I would have corrected it at that time", Margo said. "If you could snap your fingers and make El Paso's border wall disappear, would you?"
"Tonight, the President will join the millions of Americans who understand that a southern border wall is essential to border security".
"It's a stated fact that the wall has stopped crime, and it has lowered in El Paso", Sid Miller said, adding that an extended border wall is "the most humanitarian" solution to border security.
"Hopefully we'll get a chance to visit and talk about and see firsthand what the border really looks like and how we are so closely intertwined, for nearly 400 years, between El Paso and Juarez", Margo said.
He concluded, "The president is lying to you to get his border wall".
Moments before leaving the White House, Trump made it clear that O'Rourke was on his mind.
Their demonstration comes ahead of Trump's first campaign rally of the year.
Following President Donald Trump's executive order in September to erect an 18-foot steel bollard wall to replace the existing pedestrian fencing in El Paso, he called the existing chain-link fence "bad enough". "Don't take the bait".
