President Trump tweeted late Saturday that no one will be allowed to cross the border into the U.S. without being properly processed, and vowed that he would close the entire southern border with Mexico if the situation there gets out of hand. On Sunday, at noon ET, there is a group from the caravan expected to march on the point of entry in San Ysidro, California, Fox News has reportedly confirmed.

Migrants at the Southern Border will not be allowed into the United States until their claims are individually approved in court. We only will allow those who come into our Country legally. Other than that our very strong policy is Catch and Detain. No “Releasing” into the U.S...

....All will stay in Mexico. If for any reason it becomes necessary, we will CLOSE our Southern Border. There is no way that the United States will, after decades of abuse, put up with this costly and dangerous situation anymore!

Fox News said that they have confirmed through one of the organizations supporting the march, Pueblo Sin Fronteras, "that members of the caravan are expected to march peacefully to the point of entry at San Ysidro," on Sunday to attempt to cross the border into the U.S.

The news comes after confusion on Saturday, when it was reported President Trump had reached a deal with Mexico over their housing the members of the caravan until such time as they can be processed and their cases adjudicated by the American courts. Authorities with the incoming Mexican government later denied that reporting and said there was no deal in place.
