Border-state Democrats are warning this week that the Senate’s immigration reform bill would increase the number of migrant deaths.

Behind the leaders of the Congressional Hispanic Caucus (CHC), the lawmakers said the Senate’s border-security provisions – sponsored by Sens. Bob Corker (Tenn.) and John Hoeven (N.D.) – would “militarize” the border at the expense of migrant lives.

“Since 9/11 we’ve seen increasing deaths of migrants despite decreasing crossing attempts,” Rep. Beto O’Rourke (D-Texas) told reporters Wednesday outside the Capitol. “So I think it’s logical to assume that if we continue to wall up, militarize and fortify the border, we’re going to push those fewer and fewer migrants who choose to cross into more treacherous territory, thereby ensuring greater death and suffering.
