Arizona Republican Sen. Jeff Flake joined colleagues in sending a letter to President Trump urging the immediate stop to an immigration policy separating children from families seeking political asylum. Flake said his legislation would be a middle ground between the previous and current administration's policy.

“I’ve got to assure that with asylum claims that you don’t ever have separation whether that family presents itself at the checkpoint or elsewhere on the border,” said Flake.

Since the zero-tolerance policy has been in full effect, thousands of children have been separated from their parents.
