President Donald Trump on Tuesday suggested that the U.S. had no laws to prevent migrants from entering the U.S. without permission.

During a joint press conference with the leaders of the Baltic States, Trump was asked about his plan to secure the U.S.-Mexico border with military troops.

"The Mexican border is very unprotected by our laws," the president insisted. "We have horrible and very unsafe laws in the United States. And we're going to be able to do something about that hopefully soon, Congress will get their act together and create some very powerful laws like Mexico has and like Canada has and almost all countries have."

"We don't have laws," Trump complained. "We have catch and release. Catch and then you immediately release and people come back years later for a court case, except they almost never come back. So we are preparing for the military to secure our border between Mexico and the United States."

Trump also referenced a so-called "caravan" of migrants marching to the U.S. from Honduras.

"We have to have strong borders, we need to wall," he said.
