President Donald Trump made a new threat Wednesday to send armed soldiers to the U.S.-Mexico border.
Trump tweeted Wednesday that "Mexico's Soldiers recently pulled guns on our National Guard Soldiers, probably as a diversionary tactic for drug smugglers on the Border," but he didn't support the drug-smuggling claim.
He tweeted: "Better not happen again! We are now sending ARMED SOLDIERS to the Border. Mexico is not doing nearly enough in apprehending & returning!"
U.S. troops are already at the border to help reduce illegal crossings.
Two U.S. soldiers in a remote area of Texas recently were confronted on April 13 by Mexican soldiers who thought the Americans had crossed into Mexico. The Mexican troops reportedly removed a weapon from one of the American soldiers.
Mexican President Andres Manuel Lopez Obrador promised at a Wednesday news conference to investigate the border incident.
"We are going to analyze this incident, we are going to take account of what he (Trump) is indicating and will act in conformity with the law, within the framework of our sovereignty," Obrador said.
He added: "We are not going to fight with the government of the United States. The most important thing is that we want a relationship of mutual respect and cooperation for development."
Trump recently backed off his threat to seal the entire border, citing Mexican cooperation.
