Rising Democratic star and possible 2020 contender asks whether the United States 'can it still be managed by the same principles that were set down 230-plus years ago?' Reaction and analysis from Fox News senior judicial analyst Judge Andrew Napolitano.
As he explores a run for president in 2020, O'Rourke has condemned Trump's demand for a wall on the southern border.
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".
Beto O'Rourke speaks to Oprah Winfrey on stage during a taping of her TV show in the Manhattan borough of New York City, New York, U.S., February 5, 2019.
On the other side of the debate, Trump's campaign put out a video highlighting the need for a wall and featuring El Paso residents. During the event, he will be speaking to counter what he calls the "lies and a false narrative about the U.S. -Mexico border" that the president will promulgate.
As of 2014, Federal Bureau of Investigation data show El Paso still had the third lowest violent crime rate among 35 USA cities with a population over 500,000 - just as it did before the fence was built.
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".
CNN noted at the time that the connection was inaccurate, and Margo, a Republican, told CNN's Poppy Harlow and Jim Sciutto on "Newsroom" Monday that the drop in crime came prior to the barrier construction, and that Trump was "wrong" when he claimed otherwise. The president has stated he is considering declaring a national emergency to construct the wall without the approval of Congress.
A former congressman who excited grassroots Democrats last November with an against-the-odds near upset of Republican Senator Ted Cruz, O'Rourke is from El Paso.
But on Monday O'Rourke downplayed the impact his speech would have on a potential presidential campaign.
