Mariana Barros, a spokesperson for the Mexican consulate in Los Angeles, told BuzzFeed News that “we don’t have any comment at this time” on the incident.

A spokesperson for the U.S. Embassy in Mexico City told BuzzFeed News that they had no comment on Lopez’s case.

On the floor of the Senate, however, Republican Sens. John Cornyn and John Thune tried to allay the fears of many on the right. Sen. John Cornyn, R-Texas, told the Senate floor that there was a “great deal of concern” over the “ongoing humanitarian crisis unfolding in Mexico” caused by Mexican drug cartel violence, and that “we should stand in solidarity with the Mexican government and with the Mexican people — not just the drug cartel threat but the threat of radical Islam, the threat of anti-immigrant extremism — the threat of a weak Mexican economy. There’s a great deal of apprehension about what may be out there. So I have to ask you today as our friend and ally, as our military ally and as our strategic partner in a critical region of the world… to keep in mind the real fear, the real panic and the real concern.”

The U.S. has been arming and training Mexican marines in recent years.

Sen. John McCain, R-Ariz., who had a tough time with Trump during last year’s presidential race, told an audience at the National Hispanic Christian Leadership Conference that he couldn’t “expect” Trump to back away from his proposed border wall and vowed that he would continue to press him on other issues.

“I’m very happy if we don’t see Mexico make a move that would threaten the Mexican people,” McCain said, “but I want to see their policy evolve so that if they ever attempt it, they’re going to have a very costly and very difficult struggle.”

“We have two-and-a-half billion pesos in trade that go to them every single day,” McCain added. “We hope to negotiate very easily on those trade flows. But it is a challenge to our national security, to my understanding.”
