Alabama Rep. Mo Brooks got into a shouting match with CNN’s John Berman during an interview Friday morning over Donald Trump’s demand for a border wall and his threat to declare a national emergency to circumvent Congress and fund it.

Berman kicked off the interview by confronting Brooks with his 2015 comments bashing then-president Obama for using executive authority to buck Congress.

“Why does it appear you have one set of rules for President Obama, and another for President Trump?” Berman asked.

Brooks responded with a testy ad hominem: “Well John, once again you guys at CNN are misleading the public.”

The Alabama Republican argued the circumstances are different, stating there is a “national emergency of major proportions” at the border.

“So if you want to talk apples and apples, let’s do it, but don’t make up stuff and try to mislead the public,” Brooks added.

“What’s the emergency?” Berman pressed.

CNN: Congressman, why do you think Trump has authority to declare an emergency?@RepMoBrooks: Because US code says so@JohnBerman: But in 15 you signed amicus brief objecting to Obama using executive orders. Why the different standards?

Brooks cited the number of homicides committed by illegal immigrants, as well as drug overdoses and the quantity of illegal drugs entering the United States from Mexico.

“How many dead people do you need to have John before you consider it an emergency!?” Brooks exclaimed.

Berman pointed out that the “vast majority” of heroin enters the country through ports of entry, and cited a libertarian think tank Cato Institute study that found illegal immigrants commit less crime than citizens.

Brooks dismissed that study as “political propaganda” and “false.”

The pair continued to clash over the crime rates of illegal immigrants, Trump’s demand for a border wall, emergency powers and the continued government shutdown.
