The caravan of several thousand migrants headed toward the U.S.-Mexico border has grown to a mile long, according to Fox News.

Thousands of migrants have been walking from Honduras toward the U.S. in in the last two weeks, provoking President Trump, who has threatened to end or cut foreign aid to Central American countries for not stopping the caravan.

In a series of tweets Monday, Trump criticized Guatemala, Honduras, and El Salvador for not stopping the migrants from leaving their countries. Trump said he had alerted Border Patrol and the military to what he described as a national emergency.

He also blamed Democrats for not working with Republicans to overhaul U.S. immigration laws.

“Remember the Midterms!” Trump wrote.

At the end of last week, the caravan reached Mexico. It is still more than a thousand miles away from the U.S. border, and it could take more than a month for members of the group to reach the U.S. if it stays on foot.
