CNN reports that Kevin Hassett, the chairman of the Council of Economic Advisers, said in the event of a border closure there may be special rules around "certain things" that are needed. She sent a letter to Congress last week repeating numerous Trump administration's demands, including a request to quickly deport Central American minors that cross the border alone.
"Obviously, we have to help because Central American migrants pass through our territory and we have to bring order to this migration, make sure it's legal", he said.

"If you can close down the border when you're mad at anything, what is the value of a deal?" he said. Wait times at Brownsville, Texas, were 180 minutes Monday, double the wait past year.
He said 11,000 to 12,000 commercial trucks cross the border at Nogales daily, laden with about 50 million pounds of produce such as eggplants, tomatoes, bell peppers, lettuce, cucumbers and berries.
Mexico's Foreign Minister Marcelo Ebrard said on Tuesday that backups were delaying commercial traffic at the U.S. -Mexico border at several crossings. "The fact that they're doing that means fewer people are going to come".
On Monday night, Nielsen rushed home from Europe, where she was attending G7 security meetings, to oversee the response to what administration officials are calling a dire emergency at the southern border.
