CNN Don Lemon Guest Says Donald Trump Backed Himself Into a Corner With 'BS Line' About Border Wall: 'It Defies Logic'

CNN's Don Lemon and his guests reacted with bemusement to President Donald Trump's latest attack on people and organizations that disagreed with his hardline immigration stance Monday, which were aired during a campaign rally in Texas.

Following the event, Lemon and his panel discussed Trump's belligerent appearance in El Paso, Texas, during which he attacked local politicians and media organizations for disputing his assertion that the frontier city was one of the most dangerous areas in the country before the construction of a border barrier.

Hours before the president took the stage, El Paso Mayor Donald "Dee" Margo, a Republican, told CNN that Trump was wrong to suggest declining violence in the city was a result of a border barrier built from 2006 onward.

Following Trump's State of the Union address last week, Margo tweeted: "El Paso was NEVER one of the MOST dangerous cities in the US. We've had a fence for 10 years and it has impacted illegal immigration and curbed criminal activity. It is NOT the sole deterrent."

But the president dismissed Margo's remarks—which were supported by numerous media organizations including Politifact and The Associated Press. "I don't care whether a mayor is a Republican or a Democrat," Trump told the rally crowd. "They're full of crap when they say it hasn't made a big difference.

"I heard the same thing from the fake news," he added. "They said, Oh, 'crime actually stayed the same.' It didn't stay the same. It went way down."

In response, Lemon said that Trump only respects facts that aligned with his inflexible outlook. "It defies logic," he said. "The person who is running the city of El Paso, who is the mayor, who only has the citizens of El Paso's best interests at heart, who is reading facts and giving him facts, but none of that matters because it doesn't fit with his reality.

"What the hell is going on?" an exasperated Lemon asked.

Tara Setmayer, a political commentator and board director of the pro-democracy Stand Up Republic group, suggested that Trump was consciously ignoring the facts as a way to manipulate his base.

"What's going on is gaslighting," Setmayer said. She said that president "has backed himself into a corner with the BS line from the campaign about a border wall, and creating this narrative that we were going to build a 30-foot concrete wall to wall everybody out.

"He boiled it down into this elementary style, very juvenile chant," she continued. "It's not even practical. Border security experts I've spoken to and that I've worked with in the past have said to me, 'Listen, yes, physical barriers work where necessary, in conjunction with other things like technology, like more border patrol agents, like drones."
