Good morning.

President Trump heads to the border to argue for a wall, young South Koreans try to climb out of mountains of debt and A.I. holds promise for health care. Here’s the latest:

President Trump is headed to the border city of El Paso — a Democratic stronghold in Texas — to again argue for his wall. In his State of the Union address last week, he claimed a wall in El Paso lowered crime rates there.

Not far from Mr. Trump’s rally, Beto O’Rourke, a former Democratic congressman from the city and a potential presidential candidate, will hold a major counterrally. He has pointed out that El Paso boasted one of the lowest crime rates in the country before any kind of barrier was built there.

On the ground: Ahead of the events, people cross the political spectrum in El Paso had a message for Mr. Trump: Don’t speak for us.

Looking ahead: The dueling events come as congressional efforts to reach a deal over border security faltered, bringing the government perilously close to yet another partial shutdown on Friday.
