On Wednesday, the caravan of mostly Honduran migrants exploded to a whopping 4,000 people as it approached the Mexico-Guatemala border, despite President Trump’s warnings to cut off U.S. aid.

The caravan had approximately 1,300 people on Monday and managed to balloon in just two days, tripling the number of people heading northbound towards the U.S. border just in time for the midterm elections.

The Associated Press reported Wednesday that the Hondurans were spotted in Chiquimula, Guatemala marching through rain, determined to make it the Mexican border.

Because the migrant caravan has grown to over 4,000 people, the Mexican government has sent an additional 500 police to its border with Guatemala, reported NBC News.

Just how did the migrant caravan get so big in just a matter of two days? Footage surfaced Wednesday of Honduran women with children being given cash to join the caravan.

Congressman Matt Gaetz (R-FL) sounded the alarm Wednesday and called for an investigation into the source when he tweeted out a video of women holding babies and young children being given cash to join the caravan.

President Trump issued a stern warning to Honduran President Hernandez Tuesday threatening to cut U.S. aid immediately if the caravan was not stopped.

Secretary of State Mike Pompeo will also be traveling to Mexico on Friday to discuss plans to stop the caravan.
