Former Congressman and potential 2020 Democratic nominee Beto O’Rourke questioned the “principles” of the U.S. Constitution on Wednesday, arguing that its usefulness is the “question of the moment.”

In an interview with The Washington Post, O’Rourke was asked if he believes the U.S. is capable of “dramatically [changing] its approach to a whole host of issues” or whether he holds a “dismal suspicion that the country is now incapable of implementing sweeping change.”

“I’m hesitant to answer it because I really feel like it deserves its due, and I don’t want to give you a — actually, just selfishly, I don’t want a sound bite of it reported, but, yeah, I think that’s the question of the moment: Does this still work?” O’Rourke replied.

“Can an empire like ours with a military presence in over 170 countries around the globe, with trading relationships … and security agreements in every continent, can it still be managed by the same principles that were set down 230-plus years ago?”

During the interview, O’Rourke also made an argument that the “border is already fully secured and that further investment would take it even further ‘past the point of diminishing returns'” by forcing illegal migrants into dangerous territories.

“You will ensure death,” he said of Trump’s plan to build a wall on the southern border. “You and I, as Americans, have caused the deaths of others through these walls.”

The 46-year-old, who lost his Senate race against Sen. Ted Cruz (R-TX) last November, is currently weighing up whether to run for the 2020 presidential nomination.

Last week, The Wall Street Journal reported that O’Rourke is planning a road trip to meet with voters outside his home state, while he is also scheduled for a one-to-one interview with Oprah Winfrey in New York next month as part of her “Oprah’s SuperSoul Conversations from Times Square.”
