Officialscited frustration over Trump's past statements about the border and about Monday's campaign rally, "where it is possible that false statements about El Paso will continue to be made". Tickets for the event are free, and are available on the Trump campaign website.
He's finally here in El Paso!
But several El Paso residents and experts have pushed back on the president's characterization of their city, saying it misconstrues what happened before and after parts of the border wall were erected under former President George W. Bush.
"Will be heading to El Paso very soon". "Tremendous crowd! See you later!"
O'Rourke, who lost in his bid for a U.S. Senate seat in Texas, promised to blast Trump for stoking "false fear" about immigrants and telling "lies" about his hometown El Paso, which Trump said was a unsafe place before it had a border fence.
Trump mentioned El Paso during his State of the Union address last week advocating for the wall.
The El Paso Times, responding to Paxton's claim last month, noted that violent crime in El Paso peaked in 1993 and dropped 34% between that year and 2006.
Trump made the claim last week in his State of the Union Address when he said El Paso "used to have extremely high rates of violent crime - one of the highest in the country, and considered one of our nation's most unsafe cities". "Simply put, walls work, and walls save lives".
El Paso's Republican mayor, Dee Margo, said the city had been safe for years before the wall was built.
The president's rally comes four days before the nation could fall into another government shutdown.
In January, Republican Texas Attorney General Ken Paxton told Trump during a border security roundtable that the border wall worked in El Paso.
Trump could either impose a new shutdown or declare a national emergency, giving himself power to take the money from the military, although this would likely provoke lawsuits and even more political recriminations.
