The crisis was created by Obama's DOJ breaking decades old precedent and allowing asylum claims for local crime or safety problems. This opened the floodgates so to speak. Before then valid grounds for asylum claims were (mostly) limited to the threat of harm caused by a government.

Recently, Trump's DOJ reverted policy back to the way had been for decades. This has reduced the incentive to send women and children first because domestic violence/crime are no longer grounds for asylum claims.
