Wallace to Mayorkas: Why Didn’t You Build a Wall to Prevent Border Crossing?

EXCERPT:

WALLACE: "My question is why did you allow them in the country in the first place? Why didn't you build — forgive me, a wall or a fence to stop them from walking — this flood of people coming across the dam, it looks like a highway that allows them to cross the Rio Grande." 

MAYORKAS: "It is the policy of this administration. We do not agree with the building of the wall."
