THE LEAD STORY - POSSIBLE SOLUTION TO CARAVAN CRISIS - Republican Sens. Chuck Grassley and Mike Lee have urged Homeland Security Secretary Kirstjen Nielsen to execute a "safe third country agreement" with the Mexican government, which would require members of the growing migrant caravan to stop and seek asylum there ... The third-party agreement would require asylum seekers to make their claims in their first country of arrival. The senators noted the arrangement would also take some pressure off the overworked asylum system in the U.S., which has been increasingly inundated with claims that judges must adjudicate. Some Trump administration officials have argued that the "vast majority" asylum claims are fraudulent or legally dubious.
