In the first four months of 2020, some 300 people illegally crossed into the U.S. near Yuma, Arizona.

This year, the total is 27,000. 

Hundreds of people have been crossing every day -- men, women and children walking through a gap in the border wall.

Yuma will reach triple digit temperatures this week.

But the heat isn’t keeping them from crossing.
