During a Jan. 27 phone call with Mexican President Enrique Pena Nieto, President Donald Trump reportedly threatened to send U.S. troops into the neighboring country.
The Associated Press obtained a transcript of part of the conversation, which quotes Trump as declaring "You have a bunch of bad hombres down there. You aren't doing enough to stop them. I think your military is scared. Our military isn't, so I just might send them down to take care of it."
The White House had no comment on the leaked transcript.
A Mexican journalist noted a similar version of Trump's statements, which were published on a Mexican news site on Jan. 31. That account described Trump as humiliating Nieto in the conversation.
However, Mexico's foreign relations department said in a statement that the news report "is based on absolute falsehoods."
The AP notes that Trump has used the term "bad hombres" before.
Trump reportedly put his son-in-law and White House advisor, Jared Kushner, in charge of dealing with the U.S.-Mexico dispute.
In more Trump news, the president reportedly wants to change the name of the U.S. government program Countering Violent Extremism to Countering Radical Islamic Extremism.
Unidentified sources told Reuters that the new program would focus only on Islamist extremism, not homegrown terrorists such as white supremacists.
The White House would not comment on the reported change.
