Trump said people traveling in the caravans would be kept in "massive" tent cities. "A lot of them are going to be deported," Trump said. "We're putting up massive cities of tents… we have thousands of tents, we have a lot of tents… we're going to hold them right there. We're not letting them into our country."
"It's like an invasion," he said.
The US military has deployed 5,200 troops along the border to reinforce the Border Patrol units already stationed there. Another 7,000 troops are on standby to be called upon if needed. "We hope nothing happens, but if it does, we'll be prepared," Trump said.
In Trump's view, the caravans have been professionally organized to storm the borders.
"These illegal caravans will not be allowed into the United States, and they should turn back now, because they are wasting their time," Trump said.
The other major development from the news briefing was that the administration is "finalizing a plan to end the rampant abuse of our asylum system," although Trump specified no details about whether this would be done via legislative action, an executive order, regulatory shifts or other means.
Trump said that violence initiated by members of the caravan, including "throwing stones, rocks," would be met with "maximum" response. Stones and rocks, Trump said, will be considered firearms for the military's rules of engagement, noting that members of the Mexican police had been "badly hurt."
"We will consider that the maximum that we can consider that [rock throwing], because they're throwing rocks viciously and violently," the president said in his speech.
