Just before 5 p.m. the Independent Maine senator addressed the Senate floor, arguing against a recent policy that separates children from families who cross the border.
King called the policy "drastic," saying that the act of separating children from their parents is not law, but an adopted policy.
He also noted that many of the people coming across the border with their children are asylum seekers - not illegal immigrants.
"They are coming to this country under the law, they are allowed to come to this country and then prove their case, and they should have the opportunity to prove their case," Sen. King said. " They are not illegal immigrants, they are being lumped in with illegal immigrants. They are almost entirely people who are coming here because they're fleeing violence in their own country."
King, a Christian, says he was compelled to speak on the topic after Attorney General Jeff Sessions used the Bible to defend the immigration policy.
